The adjacency state is two way because both routers have received a database description packet.

The adjacency is in the exchange state. The next step is to exchange link state request and link state update packets.

The adjacency is in the ex start state. The routers have exchanged database description packets, but still have to negotiate the starting sequence number.

The adjacency state is full. The routers are exchanging database description packets to notify each other that all link state advertisements have been received.

The PE routers of the service are responsible for learning MAC addresses.

Flooding ensures that all PEs in a fully-meshed VPLS will learn the source address of all traffic.

MAC learning reduces flooding of frames with previously learned addresses.

Multiple VPLSes on the same PE share the same MAC FDB.

Link protection tunnels are established if a router is unable to establish node protection tunnels.

Link protection tunnels are only requested for a primary LSP path.

Link protection tunnels can be created for both one-to-one or facility Fast Reroute.

Link protection tunnels detour around a failed next downstream router.
