CCNP Virtualization Practice Question

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 2 - MAC/IP Advertisement route

  Why this is correct

  Type 2 EVPN routes are used to advertise MAC addresses and optionally IP addresses. When a VTEP learns a MAC address from a local host, it generates a Type 2 route and advertises it to other VTEPs via BGP EVPN. This allows remote VTEPs to learn the MAC-to-VTEP mapping and forward traffic correctly. Type 2 routes are essential for Layer 2 and Layer 3 VXLAN EVPN operation.

• ✗

  Type 3 - Inclusive Multicast Ethernet Tag route

  Why it's wrong here

  Type 3 EVPN routes are used for the distribution of multicast or broadcast traffic in the VXLAN fabric. They advertise the VTEP's IP address and the VNI, allowing other VTEPs to join the multicast group or set up ingress replication. They do not carry MAC address information. Type 3 routes are for BUM traffic handling, not unicast MAC reachability.

• ✗

  Type 1 - Ethernet Auto-Discovery route

  Why it's wrong here

  Type 1 EVPN routes are used for Ethernet Auto-Discovery and are primarily used for fast convergence and split-horizon in multihoming scenarios. They do not advertise MAC address reachability. While they can carry information about Ethernet segments, they are not the route type that distributes MAC addresses for normal Layer 2 forwarding.

• ✗

  Type 5 - IP Prefix route

  Why it's wrong here

  Type 5 EVPN routes are used to advertise IP prefixes, typically for Layer 3 routing between subnets or for external connectivity. They are not used to advertise MAC addresses. While they are important for Layer 3 VXLAN EVPN, they do not provide the MAC address reachability information that is required for Layer 2 forwarding within a VNI.
