Question

A network engineer is deploying a VXLAN BGP EVPN fabric with 2 spine switches and 40 leaf switches. To avoid a full mesh of iBGP sessions in a single AS (65001), the engineer wants a scalable control-plane design for distributing EVPN routes between all VTEPs. What is the recommended approach?

Accepted Answer

Configure the spine switches as EVPN route reflectors and peer each leaf as a route-reflector client

Answer

Configure a full mesh of iBGP EVPN sessions directly between all leaf switches

Answer

Configure each leaf in a unique AS and use eBGP EVPN sessions to the spines with next-hop-self disabled

Answer

Configure the spines as VTEPs and originate all Type-2 and Type-5 routes from the spine layer
