A network engineer is troubleshooting a single-area OSPFv3 implementation across routers R1, R2, and R3. During the verification of the implementation, it is noted that the routing tables on R1 and R2 do not include the entry for a remote LAN on R3. Examination of R3 shows the following: 1.that all interfaces have correct addressing 2.that the routing process has been globally configured 3.that correct router adjacencies have formed What additional action taken on ​R3 could solve the problem? Enable the OSPFv3 routing process on the interface connected to the remote LAN. Use the network command to configure the LAN network under the global routing process. Force DR/BDR elections to occur where required. Restart the OPSFv3 routing process.

Refer to the exhibit. A company has migrated from single area OSPF to multiarea. However, none of the users from network 192.168.1.0/24 in the new area can be reached by anyone in the Branch1 office. From the output in the exhibit, what is the problem? There are no interarea routes in the routing table for network 192.168.1.0. The OSPF routing process is inactive.

Refer to the exhibit. A network technician is troubleshooting missing OSPFv3 routes on a router. What is the cause of the problem based on the command output? There is a problem with the OSPFv3 adjacency between the local router and the router that is using the neighbor ID 2.2.2.2. The local router has formed complete neighbor adjacencies, but must be in a 2WAY state for the router databases to be fully synchronized. The dead time must be higher than 30 for all routers to form neighbor adjacencies. The neighbor IDs are incorrect. The interfaces must use only IPv6 addresses to ensure fully synchronized routing databases.
