350-601 Network Practice Question
In a VXLAN EVPN fabric with MP-BGP, which route type is used to advertise MAC addresses and associated VNI?
⚠ Common exam trap
Cisco often tests the distinction between control plane (Type 2) and data plane (Type 3) advertisement mechanisms, tempting candidates to confuse multicast group management with MAC address learning.

Correct answer & explanation
✓
Type 2: MAC/IP Advertisement
Type 2 (MAC/IP Advertisement) routes are used in VXLAN EVPN fabrics with MP-BGP to advertise MAC addresses, their associated VNI, and optionally IP addresses. This route type enables the control plane to distribute host reachability information, allowing VTEPs to build and update their forwarding tables dynamically.
