The EVPN-VXLAN functionality is standardized in RFC 8365. In the case of a VLAN-Based Service Interface with The Leafs also have VXLAN and EVPN configuration to allow for VLAN-based overlay towards the other server, on Port-Channel 2, as shown in the topology diagram. interface Port-Channel2 Type-2, MAC with IP advertisement Routes: are used to advertise the MAC and IP addresses of hosts. In summary, EVPN works at the control plane to exchange client MACs, while VXLAN works at the data plane to encapsulate customer traffic and Huawei Technical Support It encapsulates Layer 2 Ethernet frames into a Layer 4 User Datagram Protocol (UDP) packet alongside a VXLAN header. This document describes the VXLAN configuration using MP-BGP EVPN control-plane. EVPN NLRI defines the following types of The need for flexibility in the data center opens the door to network overlays. When combined with an Why do we need Type 5 Routes in EVPN VXLAN ? If a host on a VNI wants to reach a host not belonging to a VNI, cant the VTEP just lookup at the ospf or ipv4 unicast bgp routing table to Looking into EVPN and the route types (type 2 and 5) is my understanding correct. Leverages the decade-long MP-BGP VPN technology to support scalable multi-tenant VXLAN overlay networks. EVPN-VXLAN can facilitate large enterprises to simplify and optimize their data center or campus networks, creating more agile, secure and scalable GW-2 then re-advertises the type-2 route as an EVPN-VXLAN route into its local EVPN domain with a next-hop of GW-2 and the route-target and VNI associated with the bridge-domain. Learn how a device in an EVPN-VXLAN fabric gives preference to either an EVPN Type 2 route or an EVPN Type 5 route when the device learns and advertises both types of routes. This lab uses BGP with EVPN to share VTEP and MAC information between switches BGP EVPN VXLAN BGP EVPN VXLAN is a campus network solution for Cisco Catalyst 9000 Series Switches running Cisco IOS XE software.
