BGP EVPN for VXLAN
Ethernet Virtual Private Network (EVPN) is a control plane for VXLAN that reduces ooding in the network and resolves scalability
concerns. EVPN uses MP-BGP to exchange information between VTEPs. EVPN was introduced in RFC 7432 and is based on BGP MPLS-
based VPNs. RFC 8365 describes VXLAN-based EVPN.
The MP-BGP EVPN control plane provides protocol-based remote VTEP discovery, and MAC and ARP learning. This conguration reduces
ooding related to L2 unknown unicast trac. The distribution of host MAC and IP reachability information supports virtual machine (VM)
mobility and scalable VXLAN overlay network designs.
The BGP EVPN protocol groups MAC addresses and ARP/neighbor addresses under EVPN instances (EVIs) to exchange them between
VTEPs. In OS10, each EVI is associated with a VXLAN VNI in 1:1 mapping.
