To prevent a switch from advertising routes to the switch on a certain network and from importing the routes of other switches, suppress the interface on which OSPFv3 is enabled from receiving and sending OSPFv3 packets.
Perform the following operations on the switch that runs OSPFv3.
The system view is displayed.
The OSPFv3 view is displayed.
The interface is suppressed from sending and receiving OSPFv3 packets.
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. It does not take effect on the interface of other processes.
After an OSPFv3 interface is set to silent, the interface can still advertise its direct routes using the Intra-Area-Prefix-LSA of the same switch. No OSPFv3 neighbor relationship can be set up on the interface. This enhances OSPFv3 adaptability.
