Therefore Doc doesn't install any OSPF routes learned through the Frame Relay network. Doc is declaring Sneezy as a DR and expects Sneezy to generate a network link-state. However, since Sneezy isn't a DR, it doesn't generate a network link-state, which in turn prevents Doc from installing any routes in its routing table. According to the database, the DR for the Frame Relay cloud is Sleepy. However, Sleepy doesn t see Doc as an OSPF neighbor.
Type escape sequence to abort.
That explains why Sleepy can t ping Doc, and why they don t see each other as neighbors. This is the event that triggered the problem. The broadcast model relies on the Frame Relay cloud being fully meshed. In a Frame Relay environment, if Layer 2 is unstable, as in our example, we don't recommend an OSPF broadcast network-type.
