4.10 Troubleshooting OSPF Configuration

Symptom 1: OSPF has been configured in accordance with the above-mentioned
steps, but OSPF does not run normally on the switch.
Solution: Perform the following procedure.
Local fault removal:
Check whether the protocol works normally between two directly connected routers.
The normal sign is that the peer state machine between the two routers is in the FULL
state.
Note: On a broadcast or NBMA network, if the interfaces between two routers are in
DROther state, the peer state machine between the two routers are in 2-way state,
