CCNP Routing and Switching Portable Command Guide: Configuration of Redistribution

Passive Interfaces

Router(config)#router rip

Starts the RIP routing process.

Router(config-router)#passive-interface serial0/0/0

Sets the interface as passive, meaning that routing updates will not be sent out this interface.

NOTE: For RIP, the passive-inter-face command will prevent the inter-face from sending out routing updates but will allow the interface to receive updates.

Router(config)#router rip

Starts the RIP routing process.

Router(config-router)#passive-interface default

Sets all interfaces as passive.

TIP: The passive-interface default command is useful for Internet service provider (ISP) and large enterprise net-works, where a distribution router may have as many as 200 interfaces.

Router(config-router)#no passive-interface fastethernet0/0

Activates the FastEthernet0/0 interface to send and receive updates.
