Detailed Description

In OSPF terms this class represents an interface/link; interface is too overloaded a term. The Peer class is also associated with an area. In OSPFv2 there is a one-to-one correspondence. In OSPFv3 an interface/link can belong to multiple areas.

Responsibilities: 1) Packet transmission; the outgoing queue lives here. 2) Exchange Hello packets. 3) Bring up adjacency, synchronize databases. 4) Elect designated and backup router.
