O CONFIGURE DEFAULT PASSIVE INTERFACES
If you have many interfaces on a router, then there are two possibilities for
obtaining routing information from these interfaces:
• Configure a routing protocol such as OSPF on the interfaces and redistribute
connected interfaces. But, this may cause lots of Type-5 LSAs in the network.
• Configure the routing protocol on all interfaces and manually set them as passive.
But, this may cause routing protocol traffic on these interfaces.
The solution to the above problem is to configure the routing protocol on all
interfaces and manually set the passive-interface router configuration on the
interfaces where adjacency is not desired.
With the Default Passive Interface feature, this problem is solved by allowing all
interfaces to be set as passive by default using a single passive-interface default
command. Then configure individual interfaces where adjacencies are desired
using the ‘no passive-interface’ command.

To verify the passive interfaces, use ‘show ip ospf interface’ command.
Command (in RCM) Description
passive-interface default Sets all interfaces as passive by
default.
no passive-interface <interface-
name>
Activates only those interfaces
that need to have adjacencies set.
