Question 1080
A change advisory for Baypoint Retail has two requirements: (1) install a route toward an adjacent directly connected point-to-point interface, and (2) set an OSPF router ID explicitly to avoid unexpected election. Which plan correctly handles both requirements?
Explanation
Correct Answer
Both outcomes are covered: (1) On a point-to-point interface, the route can use the egress interface without Ethernet ARP for each host. (2) An explicitly configured 32-bit router ID has priority over automatic loopback/interface selection. Neither action is a substitute for the other.
Incorrect Answers
Neither step is the requested pair: Allow equal-cost multipath when the platform and configuration permit it is for retain two equal-cost eligible OSPF routes for one prefix, and Give the backup static route AD higher than OSPF's 110 is for provide a static backup only if an OSPF route to the same prefix disappears. ECMP can install several equally preferred next hops to the same exact prefix. The proposed plan misses the two stated outcomes.
The first step covers (1), but the second addresses identify which router becomes the OSPF DR among two equal-priority routers. Higher router ID wins the DR election priority tie when both are otherwise eligible. It leaves outcome (2) unfulfilled.
The second step covers (2), but the first addresses find the next-hop IP for a learned destination prefix. The routing-table next hop identifies the neighbor to which packets should be forwarded. It leaves outcome (1) unfulfilled.
