Unicast Routing

Question Image

Refer to the exhibit. Router1 and Router2 share routes in the OSPF database, but those routes are absent from their routing tables. After checking the prefix-list configuration on both routers, the engineer verified that all networks are permitted. What action should the engineer take to resolve the issue?

  • A Configure interface Serial1/0 on Router1 as a point-to-point interface
  • B Configure the two routers with different process IDs
  • C Switch the DR and BDR roles between the two routers
  • D Configure the two routers with different hello and dead timer values
Explanation

Router1 advertises the serial segment as a broadcast network with DR/BDR roles, whereas Router2 advertises it as point-to-point. This OSPF network-type mismatch creates inconsistent link-state information and prevents route installation. Configuring Router1 Serial1/0 as point-to-point makes both ends use the same network type, which is appropriate for a two-router serial link. Cisco: Troubleshoot OSPF Route Database Issues
