CCNP Virtualization Practice Question
A network engineer is deploying a VXLAN EVPN fabric with Cisco Nexus 9000 switches. The design requires that when a leaf switch learns a MAC address from a local host, remote leaf switches should be able to install that MAC into their forwarding tables without flooding. Which EVPN route type is used to advertise MAC address reachability?
⚠ Common exam trap
Many exam-takers confuse the EVPN route types, especially mixing up Type 2 MAC advertisement with Type 3 BUM replication.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Type 2 MAC/IP Advertisement route
EVPN Type 2 MAC/IP Advertisement routes are specifically designed to advertise host MAC and IP addresses along with the originating VTEP. Remote leaf switches receive these routes and program the MAC into their forwarding tables, enabling known unicast traffic to be sent directly without flooding. Other EVPN route types serve different purposes such as multihoming, BUM replication, or Layer 3 prefix advertisement.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Type 5 IP Prefix route
Why it's wrong here
Type 5 IP Prefix routes advertise IP prefixes for Layer 3 routing between VRFs, enabling inter-subnet forwarding in EVPN. They do not advertise MAC addresses for Layer 2 host reachability. Using Type 5 for MAC learning would be incorrect because it operates at the IP prefix level and does not provide the MAC-to-VTEP mapping needed for Layer 2 forwarding.
- ✗
Type 3 Inclusive Multicast Ethernet Tag route
Why it's wrong here
Type 3 Inclusive Multicast Ethernet Tag routes are used to advertise VTEP membership for BUM traffic replication, not for individual MAC reachability. They help build the multicast or ingress replication list so broadcast and unknown unicast frames reach all VTEPs. They do not carry host MAC addresses, so they cannot populate remote forwarding tables for known unicast traffic.
- ✓
Type 2 MAC/IP Advertisement route
Why this is correct
Type 2 MAC/IP Advertisement routes carry the MAC address, IP address, and VTEP information for a host, allowing remote leaf switches to install the MAC into their forwarding tables without flooding. This route type is the core of EVPN MAC learning and enables efficient unicast forwarding across the VXLAN fabric. It directly satisfies the requirement for MAC reachability advertisement.
- ✗
Type 1 Ethernet Auto-Discovery route
Why it's wrong here
Type 1 Ethernet Auto-Discovery routes are used for fast convergence and split-horizon in multihoming scenarios, not for advertising individual MAC address reachability. They help with all-active multihoming and mass withdrawal but do not carry the MAC-to-VTEP mapping used for forwarding. Relying on Type 1 for MAC learning would not populate remote forwarding tables correctly.
