When troubleshooting a BGP EVPN issue, which of the following would you check first?

VXLAN tunnel encapsulation type

A network engineer is configuring BGP EVPN on a Dell SONiC leaf switch. The engineer has configured the BGP EVPN address family and has established a session with the route reflector. However, the engineer notices that the leaf is not receiving any EVPN routes from the route reflector. The engineer has verified that the BGP session is up and that the route reflector is configured correctly. What is the most likely cause of this issue?

The leaf is not configured with the correct anycast gateway MAC.

The leaf is not configured with the correct route target import.

The leaf is not configured with the correct VNI mapping.

The route reflector is not configured to advertise the EVPN address family.

A host cannot reach a remote subnet in a VXLAN EVPN fabric. Which of the following is a common cause?

The VXLAN tunnel source IP is not reachable from the host

Incorrect VNI-to-VLAN mapping on the egress VTEP

The anycast gateway MAC is not advertised in BGP

The underlay routing protocol is not configured

What is a key characteristic of symmetric IRB in a VXLAN EVPN fabric?

Routing occurs only on the ingress VTEP, and the egress VTEP performs bridging only

Both ingress and egress VTEPs perform Layer 3 routing for inter-subnet traffic

A single VTEP is responsible for routing all inter-subnet traffic in the fabric

Routing is performed only on the egress VTEP, while the ingress VTEP bridges the traffic
