Question

• CNotification of ESI labels
• DMAC/IP binding

• A
  4% (1)
• B
  79% (19)
• C
  17% (4)

Explanation

EVPN Type-2 is the MAC/IP Advertisement Route, designed specifically to distribute MAC addresses and their associated IP bindings across the fabric. It serves as the primary mechanism for notifying remote PEs of locally learned MAC addresses (B), and it optionally carries a paired IP address to enable MAC/IP binding (D) - supporting ARP/ND proxy functions so remote PEs can answer ARP requests locally.

Why A is wrong: Batch/mass relocation (withdrawal) of MAC addresses is handled by Type-1 (Ethernet Auto-Discovery) routes, which allow a PE to withdraw many MACs at once using a single route rather than individual Type-2 withdrawals - this is the "mass withdrawal" optimization.

Why C is wrong: ESI label distribution is also a function of Type-1 routes (per-EVI A-D routes carry ESI labels for aliasing/split-horizon), and Type-4 (Ethernet Segment Route) handles ESI-based designated forwarder election - neither belongs to Type-2.

Memory tip: Think of Type-2 as the "MAC + IP postcard" - it announces who is here (MAC learned) and what address they hold (MAC/IP pair). If a route type does something other than announcing individual MAC or IP info, it's a different type (Type-1 for bulk/ESI, Type-4 for segment elections).
