OSPF Hello Packet Information
- Exchange – routing information is exchanged using the DD and LSR (Link State Request) packets.
- Loading – LSR packets are sent to neighbors requesting any new LSA’s that were found while in the “Exchange” state.
- Full – all LSA information is synchronized among adjacent neighbors.
-
- Note: on a BMA network, Hello packets are sent out, and each listening router then adds the originating router to its neighbor database. The responding routers will reply with all their Hello information so that the originating router can add them to its own neighbor databse.
