Detailed Description

template<typename A>
class Peer< A >

A peer represents a single area and is bound to a PeerOut.

RIP Peer.

A RIP peer is a host that sent RIP packets, originating routes, to the local RIP Port (Port) that have originated routes. Most of a Peer's work is conducted by the Port associated with the Peer instance. The Peer class just acts as a container of information about the Peer host, such as the number of packets sent, the time of last update, etc. It also contains the original routes as received from the Peer host. Those routes are used to push them whenever the routing policy is modified.
