A network administrator is troubleshooting an OSPF problem that involves neighbor adjacency. What should the administrator do?
- Make sure that the router priority is unique on each router.
- Make sure that the DR/BDR election is complete.
- Make sure that the router ID is included in the hello packet.
- Make sure that the hello and dead interval timers are the same on all routers.
Explanation: For OSPF to establish a neighbor adjacency, certain parameters must match between neighboring routers. The Hello and Dead intervals are among these essential requirements; if these timers are not identical on the connected interfaces, the routers will fail to form an adjacency. Other requirements for adjacency include matching subnet masks, matching OSPF area IDs, and matching OSPF network types. While router IDs must be unique, the timers must be consistent across the link.
