ccna 200 301 material.These three commands will provide you with information about which interface is starting OSPFv3: showipv6protocols, showipv6ospfinterfacebrief, and show ipv6 ospf interface0. All three commands list which interface OSPFv3 is starting on. The first two commands list brief information, while the third lists output information on many interfaces. (If you want a quick answer, choose any of the first two.)Note that all three commands list both passive and non-passive OSPFv3 interfaces-a handy example of being able to understand when to troubleshoot a neighbor transaction. To see the implications. see Example 17-5. but first note that the command passive-interface gigabitethernetO/O.ll to be added to R1's OSPFv3 process before collecting the output in the example.359 Chapter 17 Implementing IPv6 OSPF Example 17-5 Verifying the 0SPFV3 Interface and Related ParametersRl# showipv6 protocols IPv6 Routing Protocol is "connected" IPv6 Routing Protocol is "ND" IPv6 Routing Protocol is "ospf 1"Interfaces(Area 0): GigabitEthernetO/0.12 GigabitEthernetO/O.llInterfaces(Area 4): GigabitEthernetO/1Interfaces(Area 23): Serial0/0/l Serial0/0/0Redistribution: NoneAs you can see in the example, the output of the showipv6 protocols command lists the five OSPFv3 interfaces on router R1, including a passive interface G0/0.11o Troubleshooting OSPFv3 InterfacesMuch of the discussion about OSPFv3 troubleshooting revolves around resolving problems that occur between two OSPFv3 neighbors. However, errors in interface subcommands do cause many OSPF neighbor problems. To begin our discussion, think about the issues mentioned in this chapter regarding interface subcommands. /§15. the wrong area was configured using the ipospfprocess-idareaarea-idinterface subcommand, which would prevent neighbor relationships outside the interface.
