350-601 Network Practice Question
Which VXLAN EVPN route type is used for discovering VTEPs and building the BUM forwarding tree?
⚠ Common exam trap
Cisco often tests the distinction between Route Type 2 (MAC/IP advertisement) and Route Type 3 (BUM tree), so the trap here is that candidates mistakenly associate MAC address learning (Type 2) with VTEP discovery, when in fact Type 3 is the dedicated route for building the BUM forwarding tree and discovering remote VTEPs for broadcast and unknown traffic.

Correct answer & explanation
✓
Type 3
B is correct because VXLAN EVPN Route Type 3 (Inclusive Multicast Ethernet Tag Route) is specifically used to advertise the VXLAN tunnel endpoint (VTEP) IP addresses and the VNI (VXLAN Network Identifier) for BUM (Broadcast, Unknown unicast, Multicast) traffic. This route type enables the discovery of remote VTEPs and builds the multicast forwarding tree (either via ingress replication or PIM-based multicast) necessary for BUM traffic delivery in a VXLAN EVPN fabric.
