350-601 Network Practice Question
An engineer is configuring a VXLAN EVPN fabric. Which address family must be enabled under BGP to exchange MAC/VTEP reachability information?
⚠ Common exam trap
Cisco often tests the distinction between 'l2vpn vpls' and 'l2vpn evpn' — candidates mistakenly choose VPLS because it also deals with Layer 2 overlays, but VXLAN EVPN specifically requires the EVPN address family, not VPLS.

Correct answer & explanation
✓
address-family l2vpn evpn
In a VXLAN EVPN fabric, BGP is used as the control plane to exchange MAC and VTEP reachability information. The correct address family for this is 'l2vpn evpn' (address-family l2vpn evpn), which carries EVPN NLRI (Network Layer Reachability Information) as defined in RFC 7432. This enables the distribution of MAC addresses, IP-to-MAC bindings, and VTEP endpoints across the overlay network.
