350-601 Network Practice Question
In a VXLAN EVPN fabric using BGP as the control plane, which BGP address family is used to exchange MAC/VTEP reachability information between VTEPs?
⚠ Common exam trap
Cisco often tests the distinction between VPNv4 unicast (used for MPLS L3VPN) and L2VPN EVPN (used for VXLAN EVPN), so the trap here is confusing the control-plane address family for Layer 3 VPNs with the one for Layer 2 EVPN overlays.

Correct answer & explanation
✓
L2VPN EVPN
In a VXLAN EVPN fabric, the L2VPN EVPN address family (AFI 25, SAFI 70) is used to exchange MAC/VTEP reachability information between VTEPs. This address family carries BGP EVPN routes (type-2 for MAC/IP advertisements) that include the MAC address, VNI, and VTEP IP, enabling the control plane to distribute host reachability without flooding.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
IPv4 unicast
Why it's wrong here
IPv4 unicast does not carry MAC/VTEP info.
- ✗
IPv6 unicast
Why it's wrong here
IPv6 unicast is for IPv6 routes, not MAC/VTEP.
- ✗
VPNv4 unicast
Why it's wrong here
VPNv4 is for MPLS L3VPN, not VXLAN.
- ✓
L2VPN EVPN
Why this is correct
L2VPN EVPN is the correct address family for VXLAN EVPN.
