Route Type 1: Ethernet Auto-Discovery (AD) Route
The Ethernet (AD) routes are advertised on per EVI and per ESI basis. These routes are sent per ES. They
carry the list of EVIs that belong to the ES. The ESI field is set to zero when a CE is single-homed.
Route Type 2: MAC/IP Advertisement Route
The host's IP and MAC addresses are advertised to the peers within NRLI. The control plane learning of MAC
addresses reduces unknown unicast flooding.
Route Type 3: Inclusive Multicast Ethernet Tag Route
This route establishes the connection for broadcast, unknown unicast, and multicast (BUM) traffic from a
source PE to a remote PE. This route is advertised on per VLAN and per ESI basis.
Route Type 4: Ethernet Segment Route
Ethernet segment routes enable to connect a CE device to two or PE devices. ES route enables the discovery
of connected PE devices that are connected to the same Ethernet segment.
