[ 47 ] CCNP ROUTE 642-902 Quick Reference by Denise Donohue CHAPTER 3 OSPF OSPF Neighbor Relationships OSPF routers send out periodic multicast packets to introduce themselves to other routers on a link. They become neighbors when they see their own router ID included in the Neighbor field of the Hello from another router. Seeing this tells each router that they have bidirectional communication. In addition, two routers must be on a common subnet for a neighbor relationship to be formed.
Step 5. Exchange state: Step 6. Loading state: Each router compares the DBD received to the contents of its LS database. It then sends a LSR for missing or outdated LSAs. Each router responds to its neighbor’s LSR with a Link State Update. Each LSU is acknowledged. Step 7. Full state: The LSDB has been synchronized with the adjacent neighbor. Planning for OSPF Planning an OSPF implementation is more stringent than planning for EIGRP, because OSPF has specific network design requirements. Gather the following information: n Current network setup and future requirements: Document the IP addressing used and the network topology, including links types, bandwidth, and utilization.

[ 51 ] CCNP ROUTE 642-902 Quick Reference by Denise Donohue CHAPTER 3 OSPF A way to override the default RID selection is to statically assign it using the OSPF router-id command. Router ID is typically statically assigned for predictability should a process be forced to unexpectedly restart. 1 Verify and Troubleshoot OSPF The neighbor initialization process can be viewed using the debug ip ospf adjacencies command. The neighbor table can be seen with show ip ospf neighbors, which also identifies adjacency status and reveals the designated router and backup designated router.
