The silent-interface command disables an interface from receiving and sending OSPF packets. The undo silent-interface command restores the default setting. By default, the interface is permitted to

If you are connecting 2 switches there might be some consideration of whether to implement a dynamic routing protocol or whether to just use static routes for the remote subnets.

There are two different ways that I can think to make this work. One is to do MC-LAG from the 8360''s and set up the LAG interfaces on both ends as ROPs. The other way would be to

To ensure that OSPF routing information is not obtained by the devices of a certain network and the local device does not receive routing update information advertised by other devices, you can run the
Feb 16, 2026
If the switches are connected by Ethernet then the simple thing is to use the defaults and let the OSPF operate as a broadcast connection. I do not see much advantage in changing it to point
Aug 24, 2025
After an OSPF interface is set to be in the silent state, the interface can still advertise its direct routes. Hello packets on the interface, however, will be blocked and no neighbor relationship can be

OSPF works on port no. 89 and uses [AD value 110]. OSPF creates or constructs a topological map of the network from the available router by gathering link-state routing protocol.
May 21, 2026
In this scenario, IP addresses of the interfaces connecting the core switch to the BRASs and firewalls and OSPF need to be configured on the core switch, so as to implement connectivity
Mar 10, 2026
The silent-interface command in OSPF configures an interface to suppress Hello packets, preventing neighbor relationships while still advertising network routes.
