Question 1060
A branch design for Granite Works has two requirements: (1) interpret an L entry for a router's own IPv4 interface address, and (2) interpret a directly connected interface network versus remote learned network. Which plan correctly handles both requirements?
Explanation
Correct Answer
Both outcomes are covered: (1) Local routes identify IP addresses assigned to the router itself. (2) Directly connected prefixes have an attached interface, while remote routes require a next hop or recursion. Neither action is a substitute for the other.
Incorrect Answers
Neither step is the requested pair: Configure the matching OSPF area number on their shared link is for make two routers with mismatched OSPF area IDs become neighbors, and Configure the target prefix with the valid outgoing point-to-point interface is for install a route toward an adjacent directly connected point-to-point interface. OSPF neighbors must agree on the area for an eligible adjacency. The proposed plan misses the two stated outcomes.
The first step covers (1), but the second addresses recognize a route learned through single-area OSPF in the routing table. Cisco IOS uses an O routing protocol code for ordinary OSPF intra-area routes. It leaves outcome (2) unfulfilled.
The second step covers (2), but the first addresses elect the designated router on a broadcast multiaccess segment. Broadcast OSPF uses a DR/BDR election based on configured priority and router-ID tie breaks. It leaves outcome (1) unfulfilled.
