How can an OSPF neighbor relationship with a device on a certain interface be prevented

To stop devices from becoming OSPF neighbors on a particular interface, run the silent-interface command on the OSPF view.

If the devices have a large number of interfaces, configuring the silent-interface command on each of the interfaces is difficult. In this case, configure all the interfaces as silent by using a single silent-interface all command. Then, cancel the prohibition of neighbor relationship establishment on interfaces where a neighbor relationship needs to be established by running the undo silent-interface command.
