MAC/IP Advertisement Route

EVPN Type 2 route that advertises a host's MAC address and optionally its IP address, with L2 and L3 VNIs or labels.

Definition

Type 2 routes replace data-plane MAC learning and populate ARP suppression caches. A MAC mobility extended community with a sequence number handles host moves between VTEPs.

Example

[2]:[0]:[0]:[48]:[0050.56aa.0001]:[32]:[10.1.1.10]

Exam tip

A Type 2 route with an IP is what enables ARP suppression and symmetric IRB host routes.
