A RIP Port is an origin and sink of RIP packets. It is uniquely identified by the tuplet of <interface, virtual interface, address>. The Port sends and receives RIP packets via an attached Port IO object (PortIOBase<A>). The Port contains a list of Peers (Peer<A>) that it has received communication on and is responsible for updating information sent by peers in the RIP route database (RouteDB<A>).
