capitulo 8 cisco ccna 2.! The following command is from R2R2> show ip ospf interface brief|3i0/l 2 10.1.22.2/24 1 WAIT 0/0nGi0/0 2 10.1.1.2/24 1 WAIT 0/0The showip interface brife state on R1 and R2 breaks down the problem.Generally, the output listed by the show ip ospf interface brief command is similar to the show ip eigrp interface command, with each enabled interface displayed as a single line (the showip ospfinterface command displays detailed OSPF information for each interface, but it is not shown in this example).11.2 Base Content 231Specifically for this problem, Example 11-5 shows that both LAN interfaces of R1 and R2 have OSPF enabled,but this command also lists the area number of each interface, where both LAN interfaces of R2 are in area 1. In addition, these commands repeat the IP address and subnet mask for that interface, so you can see that R1's IP address 10.1.1.1/24 is in the same subnet as R2's 10.1.1.2/24, so that both routers would be on the same subnet but in different OSPF areas.232 Chapter 11 Troubleshooting IPv4 Routing ProtocolsExample 11-6 gives another way to look at the problem and runs the showip protocols command on both R1 and R2. Because this command lists out OSPFnetwork commands in shorthand form, it is able to point out possible configuration errors, even if the configuration is not yet available.
