BasicConfiguration of RIP

Configuring RIP

This section explains how to enable and restart the RIP process on your system.

•Enabling RIP

After enabling see the section Customizing RIP, to learn how to customize the RIP process on your system.

Enabling RIP

You can only enable one RIP routing process on the ASA. After you enable the RIP routing process, you must define the interfaces that will participate in that routing process using the network command. By default, the ASA sends RIP Version 1 updates and accepts RIP Version 1 and Version 2 updates.

To enable the RIP routing process, perform the following step:

Detailed Steps

Command	Purpose
router rip Example: hostname(config)# router rip	This starts the RIP routing process and places you in router configuration mode.

Use the no router rip command to remove entire RIP configuration you have enabled. Once this is cleared, you must reconfigure RIP again using therouter rip command.

Customizing RIP

This section describes how to configure RIP, and includes the following topics:

•Generating a Default Route

•Configuring Interfaces for RIP

Generating a Default Route

To generate a default route in RIP, use the following steps:

Detailed Steps

	Command	Purpose
Step 1	router rip Example: hostname(config)# router rip	This starts the RIP routing process and places you in router configuration mode.
Step 2	default-information originate Example: hostname(config-router):#  default-information originate	This step generates a default route into RIP.

Configuring Interfaces for RIP

If you have an interface that you do not want to participate in RIP routing, but that is attached to a network that you want advertised, you can configure anetwork command that covers the network to which the interface is attached, and use the passive-interface command to prevent that interface from sending RIP advertisements. Additionally, you can specify the version of RIP that is used by the ASA for updates.

Detailed Steps

	Command	Purpose
Step 1	router rip Example: hostname(config)# router rip	This starts the RIP routing process and places you in router configuration mode.
Step 2	network network_address Example: hostname(config)# router rip hostname(config-router)# network 10.0.0.0	This step specifies the interfaces that will participate in the RIP routing process. If an interface belongs to a network defined by this command, the interface will participate in the RIP routing process. If an interface does not belong to a network defined by this command, it will not send or receive RIP updates.
Step 3	Do one of the following to customize an interface to participate in RIP routing:
	version [1 | 2] Example: hostname(config-router):# version [1]	Specifies the version of RIP used by the ASA. You can override this setting on a per-interface basis
	passive-interface [default |if_name] Example: hostname(config-router):# passive-interface [default]	This step specifies an interface to operate in passive mode. Using the default keyword causes all interfaces to operate in passive mode. Specifying an interface name sets only that interface to passive RIP mode. In passive mode, RIP routing updates are accepted by, but not sent out of, the specified interface. You can enter this command for each interface that you want to set to passive mode.
