After enabling multihoming on a municipal server ESI, ops confuses EVPN Type-1 with Type-2. What role do Type-1 Ethernet Auto-Discovery routes primarily play?
Select an answer to reveal the explanation.
Short Explanation
Type-1 is the multihoming paperwork for an Ethernet Segment—aliasing and fast mass withdraw when a link fails—not the host MAC flyer. Type-2 still advertises the servers. Mixing them up is like confusing the lease document with the tenant's name on the mailbox.
Full Explanation
Type-1 Ethernet Auto-Discovery routes are central to EVPN multihoming: per-ES and per-EVI A-D behaviors support aliasing, split-horizon context, and mass withdraw when an ESI fails. They do not replace Type-2 MAC/IP host ads. IGMP/PIM are multicast topics, and Type-1 is not a VRF default-route mechanism.
