Configure OSPF NBMA Neighbors
Configure NBMA neighbors so that the interface can participate in designated router election. All OSPF neighbors that you manually configure are NBMA neighbors.
Before you begin
Enable OSPF globally.
Ensure that the interface uses an IP address.
Ensure that the interface is NBMA.
You configure OSPF NBMA neighbors on a VRF instance the same way you configure the GlobalRouter, except that you must use VRF Router Configuration mode and the prefix ip ospf. The VRF must have an RP Trigger of OSPF. Not all parameters are configurable on non0 VRFs.
Procedure
Example
Create an NBMA OSPF neighbor.
Switch:1>enable Switch:1#configure terminal Switch:1(config)#router ospf Switch:1(config-ospf)#neighbor 198.51.100.2 priority 10
