Suppressing an Interface from Sending and Receiving OSPFv3 Packets
Context
To prevent a router from advertising routes to the router on a certain network and from importing the routes of other routers, you can suppress the interface on which OSPFv3 is enabled from receiving and sending OSPFv3 packets.
Do as follows on the router that runs OSPFv3.
Procedure
- Run system-view
The system view is displayed.
- Run ospfv3 [ process-id ]
The OSPFv3 view is displayed.
- Run silent-interface { all | interface-type interface-number }
The interface is suppressed from sending and receiving OSPFv3 packets.
Follow-up Procedure
Different processes can suppress the same interface from sending and receiving OSPFv3 packets, but the silent-interface command is valid only for the OSPFv3 interface on which the specified process is enabled, and does not take effect on the interface of other processes.
After an OSPFv3 interface is set to be silent, the interface can still advertise its direct routes through the Intra-Area-Prefix-LSA of the same router. No OSPFv3 neighbor relationship can be set up on the interface. Therefore, the OSPFv3 adaptability is enhanced.
