Vxlan multicast cisco

Dec 10, 2021 · VXLAN, or Virtual Extensible LAN, is a network virtualization technology widely used on large Layer 2 networks. VXLAN establishes a logical tunnel between the source and. A VXLAN device can learn the IP address of the other endpoint dynamically in a manner similar to a learning bridge. Multicast or unicast is used to flood broadcast, unknown unicast, and multicast traffic. VXLAN endpoints, which terminate VXLAN tunnels are known as VXLAN tunnel endpoints (VTEPs). Configuration options. IGMP snooping is the process of listening to Internet Group Management Protocol (IGMP) network traffic to control delivery of IP multicasts. Network switches with IGMP snooping listen in on the IGMP conversation between hosts and routers and maintain a map of which links need which IP multicast transmission. Multicasts may be filtered from the links which do not need them, conserving bandwidth. The multicast group used by VXLAN is administrator configurable. The traffic flow for a broadcast frame, say an ARP request, goes like this: A broadcast frame is flooded to a network segment, the VTEP for that segment encapsulates the frame in a VXLAN and IP header, and forwards it to all other VTEPs.

This completes the multicast configuration. VXLAN We need to create a Network Virtualization Endpoint (NVE) interface. This is where we configure the VNI and multicast group that we will use. We source this interface from the loopback 0 interface, use VNI 5012, and use multicast group 239.1.1.1. Here's how to configure the NVE interface:. In announcing support for the BGP EVPN control plane for VXLAN on its Nexus 9000 switches, Cisco said its Nexus 9300 leaf switches, equipped with Cisco's custom ALE ASIC, can route VXLAN overlay. OTV and VXLAN can work together with Multicast, but neither require them. Unicast OTV and VXLAN EVPN (w/ MP-BGP) are much more common. OTV and VXLAN both typically have requirements for moving broadcast, multicast, and sometimes unknown unicast around, where LISP really doesn't do that in the same way. the Cisco Nexus 9000 Series in standard Cisco Nexus switch environments. They can also use ACI mode, with hardware infrastructure ready to support the Cisco ACI solution, to take full advantage of an automated, policy-based, systems management approach using Cisco ACI. This data sheet covers standard Cisco Nexus 9500 switch deployment scenarios. The role of the Underlay Network, related to BUM traffic in the VXLAN fabric, is to transport ARP, ND, DHCP and other Layer 2 BUM (Broadcast, Unknown Unicast, and Multicast) traffic between the hosts connected to different VTEPs. For the Layer 3 Multicast traffic between hosts, there should be an overlay Multicast routing design.

Some vendors, such Cisco, supports Multicast transport and BGP-EVPN AF Control Plane (VxLAN Phase 2.0) for its Data Center switches (Nexus series) and WAN edge routers (ASR series). Others have implemented VxLAN 1.5, while certain vendors support only Multicast-based transport (VxLAN 1.0). The VXLAN EVPN Multi-Site feature can be conceptualized as multiple site-local EVPN control planes and IP forwarding domains interconnected via a single common EVPN control and IP forwarding domain. Every EVPN node is identified with a unique site-scope identifier. A site-local EVPN domain consists of EVPN nodes with the same site identifier. At the DLR click the Manage tab and then Bridging . Click the green plus sign to add a bridge: Type a name for the bridge and select a logical switch ( VXLAN ) and a distributed virtual port group (VLAN-backed). Click OK and don't forget to publish your changes. That's all there is to it. You're now bridging between a VXLAN > and a VLAN. Each VTEP joins an IP multicast group according to its VxLAN segment ID (VNID), thus reducing the flooding to only the VTEP group concerned with the learning process. This IP multicast group is used to carry the VxLAN broadcast, the unknown unicast as well as the multicast traffic (BUM). ... 33 - Cisco ACI Multipod; 32 - VXLAN Multipod. 2.1 Cisco SD Access. 2.1.a Design a Cisco SD Access solution; 2.1.a i Underlay network (IS-IS, manual/PnP) 2.1.a ii Overlay fabric design (LISP, VXLAN, Cisco TrustSec) 2.1.a iii Fabric domains (single-site and multi-site using SD-WAN transit) 2.1.b Cisco SD Access deployment; 2.1.b i Cisco DNA Center device discovery and device management.

Virtual eXtensible Local Area Network (VXLAN) VXLAN (Virtual eXtensible Local Area Network) addresses the requirements of Layer 2 and Layer 3 data center network infrastructure in the presence of VMs in a multitenant environment. It runs over the existing networking infrastructure and provides a means to "stretch" a Layer 2 network. The role of the Underlay Network, related to BUM traffic in the VXLAN fabric, is to transport ARP, ND, DHCP and other Layer 2 BUM (Broadcast, Unknown Unicast, and Multicast) traffic between the hosts connected to different VTEPs. For the Layer 3 Multicast traffic between hosts, there should be an overlay Multicast routing design. It does require a multicast infrastructure, which may make it a little more tricky to implement. The other way to handle BUM traffic is called Head End Replication. This is only available when using control plane learning, as it needs to know where the VTEPs are. ... Cisco - VXLAN Overview: Cisco Nexus 9000 Series Switches. A VXLAN tunnel is identified by a pair of VTEP IP addresses. During VXLAN tunnel establishment, the local and remote VTEPs attempt to obtain each other's IP addresses. As long as the VTEP IP addresses are reachable to each other at Layer 3, a VXLAN tunnel can be established. VXLAN tunnels can be established in either static or dynamic mode. When IPsec is being used, it is customary to set the MTU size on the tunnel interfaces to 1,400 bytes and to set the TCP-MSS-adjust to 1,360 bytes. This can be configured in a Cisco IOS device.

Virtual eXtensible Local Area Network (VXLAN) is a tunneling protocol that tunnels Ethernet (layer 2) traffic over an IP (layer 3) network. Traditional layer 2 networks have issues because of three main reasons: Spanning-tree. Limited amount of VLANs. Large MAC address tables. Spanning-tree blocks any redundant links to avoid loops. BFD packets are encapsulated in VXLAN as described below. The VXLAN packet format is defined in Section 5 of [RFC7348]. The value in the VNI field of the VXLAN header MUST be set to the value selected as the Management VNI. The outer IP/UDP and VXLAN headers MUST be encoded by the sender, as defined in [RFC7348]. Cisco VXLAN flood-and-learn technology complies with the IETF VXLAN standards (RFC 7348), which defined a multicast-based flood-and-learn VXLAN without a control plane. The original Layer 2 frame is encapsulated with a VXLAN header and then placed in a UDP-IP packet and transported across an IP network. Introduction Many MikroTik devices come with a built-in switch chips that usually have an option to do VLAN switching on a hardware level, this means that you can achieve wire-speed performance using VLANs if a proper configuration method is used.

Technical Tip: VXLAN over IPsec for multiple VLANs... - Fortinet Co..... 1 of 7 2022/1/24, 9:52 PM. VLAN uses VLAN tag on Layer 2 frame for encapsulation to extend VLAN across switches. On the other hand, VxLAN uses MAC-in-UDP encapsulation to extend Layer2 segments across locations. VLAN uses 12-bit VLAN ID which limits the scalability to 4094 VLANs. Whereas, VXLAN uses 24-bit ID which scales it up to 16 Million VXLAN segments. The VxLAN is a standardized specification created by the collaboration of VMware, Cisco, and Arista Network vendors. VxLAN is defined in the RFC 7348. a. VxLAN vs. VLAN ... The VTEP-2 and VTEP-3 belong to a multicast group used for VXLAN VNIs. The VTEP-2 checks the VxLAN ID from the packet and forwards it based on IP. The following tunnel types as defined in can be used in the PMSI Tunnel attribute for VXLAN/NVGRE: + 3 - PIM-SSM Tree + 4 - PIM-SM Tree + 5 - BIDIR-PIM Tree + 6 - Ingress Replication In case of VXLAN and NVGRE encapsulations with locally assigned VNIs, just as in , each PE MUST advertise an IMET route to other PEs in an EVPN instance for the. VXLANs use UDP destination port 8472.The VXLAN interface IP address cannot be in the same subnet as the VLAN interface. 4.1 Add a VXLAN.To add a VXLAN to an interface in the LoadMaster, follow the steps below: 1. In the main menu of the LoadMaster WUI, go to System Configuration > Network Setup and click the relevant interface link. When VXLAN was first. VXLan is now upstreamed into the Master build. It is worth mentioning that is the VXLAN framing only, not the Multicast control plane functionality. So basically no need to pull from the fork anymore but pull directly from the Open vSwitch Master or 1.10+ tarball (approximately). I have done a couple of GRE tunnel how-tos using OpenvSwitch (OVS). PIM-DM (PIM Dense Mode) PIM-DM (PIM Dense Mode) is a PIM mode which uses push model.In this model, router floods the multicast traffic to all the recipients at the first time. Firstly, the source floods the traffic to all the nodes even if they are not related in that multicast traffic. After this flood, the uninterested nodes send prune request and so the interested nodes are detected. The only way a multicast ping works is if it's sourced from the local interface on the leaf that is connected to the one spine that has the (*,g). That makes sense, but the point of the anycast config is that all the spines get (s,g) and (*,g) for a given stream. The complete guide to building and managing next-generation data center network fabrics with VXLAN and BGP EVPN This is the only comprehensive guide and deployment reference for building flexible data center network fabrics with VXLAN and BGP EVPN technologies. Writing for experienced network professionals, three leading Cisco experts address everything from standards and protocols to. Or you could configure a border leaf within the VXLAN fabric that also peers with an outside device (say an OSPF router), and share the outside routing information into the VXLAN fabric. Finally, VXLAN works well with LISP to provide L3 external connectivity. There are a number of good white papers available about VXLAN. As displayed from above output, vxlan id is 1, eth0 device is used in tunneling, VXLAN UDP port is 8472 and the nolearning tag that disables source-address learning meaning Multicast is not used but Unicast with static L3 entries for the peers. When VXLAN was first implemented in Linux 3.7, the UDP port to use was not defined. The underlay network is unaware of VXLAN. Hardware. A hardware VTEP is a router, switch, or firewall which supports VXLAN. We also call a hardware VTEP a VXLAN gateway because it combines a regular VLAN and VXLAN segment into a single layer 2 domain. Some switches have VXLAN support with ASICs, offering better VXLAN performance than a software .... Multicast is communication between a single sender and multiple receivers on a network. Typical uses include the updating of mobile personnel from a home office and the periodic issuance of online newsletters. Together with anycast and unicast , multicast is one of the packet types in the Internet Protocol Version 6 ( IPv6 ). This is not applicable to the Cisco Nexus 9200 and 9300-EX platform switchesand Cisco Nexus 9500 platform switches with 9700-EX line cards. • Beginning with Cisco NX-OS Release 7.0(3)F3(3), VXLAN Layer 2 Gateway is supported only on the9636C-RX line card.

PIM Dense Mode (PIM-DM) is the PIM mode which uses Push Model. According to this model, firstly all the multicast traffic is flooded through the recipients. All the nodes in the network receives this traffic even if they are not related in that multicast traffic. Then, the nodes that are not interested with this traffic send prune requests. We present Elmo, a system that addresses the multicast scalability problem in multi- tenant datacenters. Modern cloud applications frequently exhibit one-to-many communication patterns and, at the same time, require sub-millisecond latencies and high throughput. IP multicast can achieve these requirements but has control- and data-plane scalability limitations that make it challenging to offer.

This video demonstrates how to configure basic VXLAN beween two Cisco Nexus 9k switches without using multicast. The video covers below topic in a beginner l. Chapter 7, "Multicast Forwarding." This chapter provides details about forwarding multicast data traffic in a VXLAN BGP EVPN network. It discusses vanilla Layer 2 multicast traffic forwarding over VXLAN, as well as topics related to its evolution with enhancements in IGMP snooping. In announcing support for the BGP EVPN control plane for VXLAN on its Nexus 9000 switches, Cisco said its Nexus 9300 leaf switches, equipped with Cisco's custom ALE ASIC, can route VXLAN overlay. Cisco also supports Layer-2 transport over VXLANv6. Broadcast, Unknown Unicast, and Multicast (BUM) is handled through Ingress-Replication (aka Head-End Replication). With IPv4, IPv6 or both payloads in VXLANv6, we have to somehow make the associated endpoints reachable to the rest of the world. We present Elmo, a system that addresses the multicast scalability problem in multi- tenant datacenters. Modern cloud applications frequently exhibit one-to-many communication patterns and, at the same time, require sub-millisecond latencies and high throughput. IP multicast can achieve these requirements but has control- and data-plane scalability limitations that make it challenging to offer. VXLan is now upstreamed into the Master build. It is worth mentioning that is the VXLAN framing only, not the Multicast control plane functionality. So basically no need to pull from the fork anymore but pull directly from the Open vSwitch Master or 1.10+ tarball (approximately). I have done a couple of GRE tunnel how-tos using OpenvSwitch (OVS). Neither creates a full mesh. Multicast isn't popular anymore because most platforms are limited by the number of multicast groups supported, typically well below the 16 million+ VXLANs you get. It's one VNI to multicast group, and most underlay hardware switches anywhere between 1,000 to 8,000 mulitcast groups I think. VxLAN Bridging Configuration.

Virtual eXtensible Local Area Network (VXLAN) is a tunneling protocol that tunnels Ethernet (layer 2) traffic over an IP (layer 3) network. Traditional layer 2 networks have issues because of three main reasons: Spanning-tree. Limited amount of VLANs. Large MAC address tables. Spanning-tree blocks any redundant links to avoid loops. Figure 3-1 Single Multicast Group for All VNIs Three edge devices participate as VTEPs in a given VXLAN-based network. These VTEPs are denoted V1 (10.200.200.1), V2 (10.200.200.2), and V3 (10.200.200.3). IP subnet 192.168.1./24 is associated with Layer 2 VNI 30001, and subnet 192.168.2./24 is associated with Layer 2 VNI 30002. VXLAN is a solution to support a flexible, large-scale multitenant environment over a shared common physical infrastructure. The transport protocol over the physical data center network is IP plus UDP. VXLAN defines a MAC-in-UDP encapsulation scheme where the original Layer 2 frame has a VXLAN header added and is then placed in a UDP-IP packet. Virtual Extensible Local Area Network (VXLAN) is a Layer 3 encapsulation protocol that enables MX Series routers to push Layer 2 or Layer 3 packets through a VXLAN tunnel to a virtualized data center or the Internet. Communication is established between two virtual tunnel endpoints (VTEPs). VTEPs encapsulate the virtual. In announcing support for the BGP EVPN control plane for VXLAN on its Nexus 9000 switches, Cisco said its Nexus 9300 leaf switches, equipped with Cisco's custom ALE ASIC, can route VXLAN overlay.

Use multicast VPNs to logically separate traffic on the same physical infrastructure; Explore the unique nuances of multicast in the data center; Implement Virtual Port Channel (vPC), Virtual Extensible LAN (VXLAN), and Cisco's Application Centric Infrastructure (ACI) Design multicast solutions for specific industries or applications. As VXLAN has 16 million VNI, and mapping to each multicast group is impractical for deployment. Ingress Replication is sometime used in VXLAN, so that every VTEP must be aware of every VTEP that have membership for given VNI. Due to which source VTEP generates n copies for every multidestination frame weather some VTEP requires that frame or not. The new network topology models build well-designed hierarchical networks, but with the addition of VXLAN as an over-the-top network this hierarchy was being flattened out. While the network design in the underlying topology was predominantly Layer 3 and an efficient hierarchy was present, with the introduction of the overlay network this... 04-28-2021 10:49 AM. Hi all, hoping for a bit of help from any multicast gurus out there. I'm building the underlay network for a VXLAN setup and I can't get the multicast. This will prevent rogue VTEPs from joining legitimate multicast groups for VXLAN. PIM is disabled by default on the interface, no additional actions required. - in case IGMP is required on the interface, IGMP snooping filters can be applied, which will eliminate the possibility of joining IGMP groups used for VXLAN.

The multicast group used by VXLAN is administrator configurable. The traffic flow for a broadcast frame, say an ARP request, goes like this: A broadcast frame is flooded to a network segment, the VTEP for that segment encapsulates the frame in a VXLAN and IP header, and forwards it to all other VTEPs. When it comes to VXLAN, the multicast support requirements in the physical network are dictated by the number of transport VLAN used in the design. What is VXLAN flood and learn and multicast? ...

With functional unicast and multicast routing, we only have a couple extra ingredients to make this work. 1. Network Virtualization Endpoint (NVE) Interface 2. Service Instance 3. Bridge-Domain (to tie it all together). Luckily, the configuration is so generic, we can just copy and paste it to all our Virtual Tunnel Endpoints (VTEPs). I know. The use of VXLAN as overlay technology allows providing data link layer connectivity services between endpoints that may be deployed across network layer network domains. Since those endpoints are logically part of the same data link layer domain, they must be capable of sending and receiving data link layer multi-destination frames (BUM traffic). This includes all the usual fields, but the ones we're interested in for VxLAN are the source and destination addresses. The source address is the IP address of the VTEP that send the packet over the transport network. The destination address is the VTEP at the other end of the network.

Introduction Many MikroTik devices come with a built-in switch chips that usually have an option to do VLAN switching on a hardware level, this means that you can achieve wire-speed performance using VLANs if a proper configuration method is used. The concept of overlay networking has been around for a while, but has made a return to the spotlight with the rise of. VXLAN Tutorial. With the rapid growth of networking nowadays, traditional VLANs have to face some challenges. There are four main disadvantages of traditional VLANs: + The number of VLANs is small. A traditional VLAN ID is only 12-bit in length so it only provides 4096 VLANs. This number of VLANs is maybe enough in the old days but nowadays it. Cisco VXLAN flood-and-learn technology complies with the IETF VXLAN standards (RFC 7348), which defined a multicast-based flood-and-learn VXLAN without a control plane. The original Layer 2 frame is encapsulated with a VXLAN header and then placed in a UDP-IP packet and transported across an IP network. The multicast group used by VXLAN is administrator configurable. The traffic flow for a broadcast frame, say an ARP request, goes like this: A broadcast frame is flooded to a network segment, the VTEP for that segment encapsulates the frame in a VXLAN and IP header, and forwards it to all other VTEPs. The Virtual eXtensible Local Area Network (VXLAN) (RFC 7348) protocol has been widely adopted in the market place, with support from vendors like Cisco, Brocade, Arista, Dell, HP and others.

Ingress Replication for VXLAN EVPN is deployed when IP Multicast underlay network is not used. Ingress replication, or Headend Replication, is a unicast approach to handle multi-destination trafffic. Handling BUM traffic in a network using ingress replication involves an ingress device replicating every BUM packet and sending them as a separate. Introduction Many MikroTik devices come with a built-in switch chips that usually have an option to do VLAN switching on a hardware level, this means that you can achieve wire-speed performance using VLANs if a proper configuration method is used. The concept of overlay networking has been around for a while, but has made a return to the spotlight with the rise of. A VXLAN device can learn the IP address of the other endpoint dynamically in a manner similar to a learning bridge. Multicast or unicast is used to flood broadcast, unknown unicast, and multicast traffic. VXLAN endpoints, which terminate VXLAN tunnels are known as VXLAN tunnel endpoints (VTEPs).

Here are some of my thoughts after attending a vXLAN session by Cisco at VMworld 2012. vXLAN really just solves one problem. Most virtual infrastructures depend on L2 connectivity. vMotion is a good example of this. ... vXLAN uses IP Multicast to get traffic to where it needs to go. This means that after the VM traffic is encapsulated in IP/UDP. The initial release of VxLAN is based on unicast and multicast to deliver Layer 2 frames. As there is no EVPN support, the VTEPs must be manually configured for each endpoint in a full mesh configuration. ... Looking to replace a Q in Q (mostly 15+ year old Cisco) based metro area network (mostly fiber based with a few 5GHz links and a couple. PIM is multicast, which is used to handle BUM traffic. VxLAN adds quite a bit of overhead, so we need to increase the MTU size. If we don't do this, we may end up with fragmented packets, which can decrease performance. We also need to start the OSPF process. We'll add more OSPF config later on. VXLAN is an encapsulation protocol that provides data center connectivity using tunneling to stretch Layer 2 connections over an underlying Layer 3 network. In data centers, VXLAN is the most commonly used protocol to create overlay networks that sit on top of the physical network, enabling the use of virtual networks.. "/>.

In announcing support for the BGP EVPN control plane for VXLAN on its Nexus 9000 switches, Cisco said its Nexus 9300 leaf switches, equipped with Cisco's custom ALE ASIC, can route VXLAN overlay. Underlay Multicast Trees:-In Cisco ACI VXLAN environment , it implements and use the routed multicast trees in the underlay network to support multidestination traffic. If the bridge domain is not configured to use the mapping-database lookup, the location of the MAC of remote endpoints (VTEP IP address where endpoint is connected ) is learned. Multicast is communication between a single sender and multiple receivers on a network. Typical uses include the updating of mobile personnel from a home office and the periodic issuance of online newsletters. Together with anycast and unicast , multicast is one of the packet types in the Internet Protocol Version 6 ( IPv6 ). . Cisco recommends that you have knowledge of these topics: Multicast routing concepts such as Rendezvous€Point (RP) and Platform Independent Multicast (PIM). Virtual Port Channel. #clmel VXLAN Deployment Models - A Practical Perspective BRKDCT-2404 Victor Moreno, Distinguished Engineer. Symptom: Packets destined to TCP port 8472 are dropped from VMs that have 'TCP checksum offload' enabled - It works fine for UDP traffic - It works fine on the VMWare DVS/Standard switch - There is no VXLAN configuration at all Conditions: Happens only for TCP traffic destined to port 8472 and from VMs that have 'TCP checksum offload' enabled. Similar to VXLAN, GENEVE also encapsulates packets with a unique header and uses UDP as its mechanism of transport. Geneve supports unicast, multicast, and broadcast. Geneve defines an encapsulation data format only and does not include information for the control plane. GENEVE is developed to be flexible and extensible in the best possible way. PIM Dense Mode (PIM-DM) is the PIM mode which uses Push Model. According to this model, firstly all the multicast traffic is flooded through the recipients. All the nodes in the network receives this traffic even if they are not related in that multicast traffic. Then, the nodes that are not interested with this traffic send prune requests. This is an intro overview of VxLAN, a network overlay technology commonly used in the cloud. It is vendor independent so it can run on #Cisco #Nexus, NSX, Op. Interfaces. Virtual eXtensible Local Area Network (VXLAN) is a tunneling protocol that tunnels Ethernet (layer 2) traffic over an IP (layer 3) network. Traditional layer 2 networks have issues because of three main reasons: Spanning-tree. Limited amount of VLANs. Large MAC address tables. Spanning-tree blocks any redundant links to avoid loops. Virtual eXtensible Local Area Network (VXLAN) VXLAN (Virtual eXtensible Local Area Network) addresses the requirements of Layer 2 and Layer 3 data center network infrastructure in the presence of VMs in a multitenant environment. It runs over the existing networking infrastructure and provides a means to "stretch" a Layer 2 network. VXLAN identifier (VNI) is a 24-bit segment, which means it can provide 16 million VXLAN within same domain. Diagram source: Cisco List some of VXLAN uses Data centers (virtualized hosts) allowing VM's to communicate between two DC's Extending Layer2 (VLANS) in remote sites Multicast instead of broadcast. PIM-DM (PIM Dense Mode) PIM-DM (PIM Dense Mode) is a PIM mode which uses push model.In this model, router floods the multicast traffic to all the recipients at the first time. Firstly, the source floods the traffic to all the nodes even if they are not related in that multicast traffic. After this flood, the uninterested nodes send prune request and so the interested nodes are detected. VXLAN identifies individual layer-2 domains using a 24-bit virtual Air Force Reserve Pilot Reddit VXLAN is intended for use within a single datacenter, and therefore can afford to be a bit more promiscuous with BUM (Broadcast, Unknown Unicast, and Multicast) propagation, tunneling them inside multicast across Layer 3 Selecting Manager → Layer. type rechargeable power EVPN/vXLAN multihome without LAG physical connection question Jump to Best Answer.

The Citrix ADC sends broadcast, multicast, and unknown unicast frames over Layer 3 to the multicast group IP address of this VXLAN. Similar to a Layer 2 bridge table, Citrix ADCs maintain VXLAN mapping tables based on the inner and outer header of the received VXLAN packets. This table maps of remote host MAC addresses to VTEP IP addresses for. One of the protocols utilized in the physical network is IP multicast. VXLAN makes use of this IP multicast protocol to populate the forwarding tables in the VTEP. Before we dig into how IP multicast is utilized in VXLAN, in the next blog, we will take a look at some basics on IP Multicast. Here are the links to Part 2, Part 3, Part 4, Part 5. OTV and VXLAN can work together with Multicast, but neither require them. Unicast OTV and VXLAN EVPN (w/ MP-BGP) are much more common. OTV and VXLAN both typically have requirements for moving broadcast, multicast, and sometimes unknown unicast around, where LISP really doesn't do that in the same way. Virtual Extensible LAN (VXLAN) lets you tunnel layer 2 traffic over a layer 3 network without the disadvantages of traditional layer 2 networks. Now multicast on the underlay network is one of the methods that can be used to allow a VXLAN topology to learn the mapping between a VTEP IP address and a MAC address.
