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. Use the no ip route-cache policy interface
configuration command to disable fast-switching PBR. Use the no ip local policy route-map map-tag
global configuration command to disable policy-based routing on packets originating on the switch.
Filtering Routing Information
You can filter routing protocol information by performing the tasks described in this section.
When routes are redistributed between OSPF processes, no OSPF metrics are preserved.
Note
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. Then routing update messages are not being sent
through a router interface. When you use this command in the OSPF protocol, the interface address that
you specify as passive appears as a stub network in the OSPF domain. OSPF routing information is
neither sent nor received through that interface.
In networks with many interfaces, you do not need 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.
You can then manually setting interfaces where adjacencies are desired.
Beginning in privileged EXEC mode, follow these steps to configure passive interfaces:
Command
Step 1
configure terminal
Step 2
router {bgp | rip | ospf | eigrp}
Step 3
passive-interface interface-id
Step 4
passive-interface default
Step 5
no passive-interface interface type

Purpose
Return to privileged EXEC mode.
(Optional) Display all configured route maps or only the one
specified to verify configuration.
(Optional) Display policy route maps attached to interfaces.
(Optional) Display whether or not local policy routing is
enabled and, if so, the route map being used.
(Optional) Save your entries in the configuration file.
Purpose
Enter global configuration mode.
Enter router configuration mode.
A switch running the IP base feature set supports only the rip
keyword.
Suppress sending of routing updates through the specified Layer 3
interface.
(Optional) Set all interfaces as passive by default.
(Optional) Activate only those interfaces that need to have
adjacencies sent.
