Question: 1 / 400

What is the purpose of the passive-interface command in OSPF configurations?

To enable OSPF on the interface

To disable OSPF on all interfaces

To prevent OSPF from sending or receiving protocol packets on specified interfaces

The purpose of the passive-interface command in OSPF configurations is to prevent OSPF from sending or receiving protocol packets on specified interfaces. When you configure an interface as passive, OSPF will still acknowledge that the interface is part of the OSPF-enabled network, but it will not establish neighbor relationships or send OSPF routing updates over that interface. This is particularly useful for interfaces that connect to end-hosts or are part of a network segment where OSPF routing information is not needed, helping to enhance network security and reduce unnecessary OSPF traffic.

This command is especially relevant in scenarios where you want to limit OSPF communication while still retaining the routing capability provided by OSPF for other interfaces where dynamic routing is necessary. Interfaces designated as passive won't participate in OSPF routing advertisements but can still be used for other routing purposes or as designated paths in OSPF routes.
