    ZXR10 5900E Series User Manual (IPv4 Volume) Default Route Configuration Example A router might not be able to determine the routes to all other networks.

    ZXR10 5900E Series User Manual (IPv4 Volume) OSPF Algorithm As OSPF is a link state protocol. OSPF router generates a routing table by setting up a link state database, which contains the infor- mation of all networks and routers. Routers use this information to establish routing tables.

  • Page 23: Hello Packet And Timer

    There are only two routers in point-to-point network and virtual links. Routers set up an adjacency relationship automatically. The point-to-multipoint network can be regarded as a set of point-to- point networks. Each pair of routers set up an adjacency relation- ship automatically.

    ZXR10 5900E Series User Manual (IPv4 Volume) OSPF sends Link State Acknowledgements (LSAck) to make sure that each LSA is received by neighbors.

When a router sends an LSA to an interface, the LSA is recorded in the resend queue of the interface.
