Which command can you use to display the area border routers (ABRs) and the routes to them?
- show ip ospf dr
- show ip opsf bdr
- show ip ospf database
- show ip ospf border-routers
The correct answer is show ip ospf border-routers. The following commands are available to verify OSPF configurations:
show ip ospf border-routers – displays internal ISPF routing table entries for an ABR.
show ip ospf virtual-links – displays the current state of OSPF virtual links.
show ip ospf – displays information about the router’s role and each area to which the router is connected.
show ip ospf database – displays the contents of the router’s topological database. Note that a number of keywords can be used with the show ip ospf database command to get specific information.The command show ip ospf dr is not correct because dr is not a parameter of the show ip ospf command.The command show ip ospf bdr is not correct because bdr is not a parameter of the show ip ospf command.
