Which EVPN route type is responsible for advertising MAC addresses combined with IP addresses (MAC/IP Advertisement Route)?
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
✓
Route Type 2
Route Type 2 is the MAC/IP Advertisement Route, which carries a MAC address and optionally an IP address, facilitating both L2 bridging and L3 host routing.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Route Type 3
Why it's wrong here
Route Type 3 advertises Inclusive Multicast Ethernet Tags for BUM traffic replication, carrying no MAC or IP binding. It is tempting because it is essential for building multicast tunnels, making it correct when configuring flooding of broadcast and unknown unicast.
- ✓
Route Type 2
Why this is correct
Route Type 2 carries the MAC/IP Advertisement, binding a host MAC to its IP address and forwarding context. Type 1 advertises Ethernet Auto-Discovery, Type 3 carries Inclusive Multicast, and Type 4 handles Ethernet Segment routes, so Type 2 uniquely satisfies the MAC-plus-IP requirement.
- ✗
Route Type 4
Why it's wrong here
Type 4 carries the Ethernet Segment route, used for Designated Forwarder election on multi-homed segments, and holds no MAC or IP addresses. Type 2 is the MAC/IP Advertisement route. Type 4 is tempting because it also advertises per-ES information, but its payload is the ESI, not host addresses.
- ✗
Route Type 1
Why it's wrong here
Route Type 1 advertises Ethernet Auto-Discovery per ESI, carrying no IP address, so it cannot pair MAC with IP. It is tempting because it supports fast convergence and split-horizon, making it correct for multihoming and mass withdrawal scenarios.
