Another point to note is that one of the interfaces is a system interface. The IP address of the system interface will be used as the OSPF router ID unless a different OSPF router ID is explicitly configured. You determine the OSPF router ID using the show router ospf status command as shown in Listing 9.3. notice that the router ID is the same as the system interface, indicating that a specific OSPF router ID has not been configured.

The configuration for the interfaces and OSPF information for router r1 are shown in Listings 9.4 and 9.5. First, you must create the interfaces that will participate in the OSPF routing protocol. On router r1 we have created the system interface and two other interfaces, toR2 and toR5. You must assign them to a particular port and give them an IP address. note that the system interface does not require a port. next, you have to configure the interfaces for OSPF. You do this by creating an OSPF area ID, 0.0.0.0 in this case, and assigning interfaces to this area. As mentioned previously, the interfaces need to be configured as type point-to-point since they are Ethernet and will default to OSPF interface type broadcast by default.

Once OSPF is configured on an interface, it will begin to issue OSPF Hello messages on each interface. Other routers will see the Hello messages and will eventually form an adjacency with r1 and exchange link state database information. You can easily see a router s OSPF neighbors using the show router ospf neighbor command as shown in Listing 9.6. note that r1 has two neighbors in a Full state, indicating that they have formed an adjacency and exchanged full link state database information.

In a single area point-to-point network, only the router LSAs (Type 1 LSAs) will be used to create the link state database. In more complex topologies, there are other types of LSAs exchanged. In the next section, we examine the process by which LSAs are flooded throughout a network in response to a change in the network.
