VXLAN

Enterprise SONiC Switch 1 and Switch 2 are components of a symmetric VXLAN fabric in a data-center environment. Switch 1 has learned MAC addresses from its local VLANs.

What is the role of BGP EVPN in this scenario?

  • A Distributes locally learned MAC addresses to Switch 2
  • B Establishes Layer 2 connectivity between Switch 1 and Switch 2
  • C Enables efficient communication across the VXLAN fabric
Explanation

BGP EVPN distributes locally learned MAC reachability information through EVPN MAC/IP Advertisement routes to other participating switches. This enables Switch 2 to install reachability information for MAC addresses learned by Switch 1.
