Chapter 31 Configuring IP Unicast Routing
Configuring Protocol-Independent Features
Use the no route-map map-tag global configuration command or the no match or no set route-map
configuration commands to delete an entry. Use the no ip policy route-map map-tag interface
configuration command to disable PBR on an interface.
Filtering Routing Information
You can filter routing protocol information by performing the tasks described in this section.
Note When routes are redistributed between OSPF processes, no OSPF metrics are preserved.
Setting Passive Interfaces
To prevent other routers on a local network from dynamically learning about routes, you can use the
passive-interface router configuration command to keep routing update messages from being sent
through a router interface. When you use this command in the OSPF protocol, the interface address you
specify as passive appears as a stub network in the OSPF domain. OSPF routing information is neither
sent nor received through the specified router interface.
In networks with many interfaces, to avoid having to manually set them as passive, you can set all
interfaces to be passive by default by using the passive-interface default router configuration command
and manually setting interfaces where adjacencies are desired.
