An administrator types in the command router ospf 1 and receives the error message:
“OSPF process 1 cannot start.” (Output is omitted.) What should be done to correctly set up OSPF?

During a recent OSPF election among three routers, RTA was elected the DR and RTB was
elected the BDR, as seen in the graphic. Assume that RTA fails, and that RTB takes the place of
the DR while RTC becomes the new BDR. What will happen when RTA comes back online?

Refer to the exhibit.

During the process of configuring a virtual link to connect area 2 with the
backbone area, the network administrator received this console message on R3:
*Mar 1 00:25:01.084: %OSPF-4-ERRRCV: Received invalid packet: mismatch area ID, from
backbone area must be virtual link but not found from 20.20.20.1, Serial 0
How should the virtual link be configured on the OSPF routers to establish full connectivity
between the areas?

OSPF is configured over a Frame Relay network as shown in the exhibit. All PVCs are active.
However, R1 and R3 fail to see all OSPF routes in their routing tables. The show ip ospf neighbor
command executed on R2 shows the state of the neighbors. What should be done to fix the problem?

Refer to the exhibit.

In the show ipv6 route output, what would the metric be for a summary route that summarizes all
