Step 1. Examine the internetwork design to determine on which interfaces the routing protocol should be enabled and which routers are expected to become neighbors.
Step 2. Verify whether the routing protocol is enabled on each interface (as per Step 1). If it isn’t, determine the root cause and fix the problem.
Step 3. Verify that each router has formed all expected neighbor relationships. If it hasn’t, find the root cause and fix the problem.
