Detailed Description

Neighbour specific information.

enum State { Down = 1, Attempt = 2, Init = 3, TwoWay = 4, ExStart = 5, Exchange = 6, Loading = 7, Full = 8 }

State

The ordering is important (used in the DR and BDR election).

 Neighbour (Ospf<A>& ospf, Peer<A>& peer, OspfTypes::RouterID router_id, A neighbour_address, OspfTypes::NeighbourID neighbourid, OspfTypes::LinkType linktype, State state = Init)

Neighbour

We start in Init not Down state as typically this class is created on demand when a hello packet arrives.
