Chapter 9 Configuring IP Routing

Configuring RIP

Devices that support RIP send routing-update messages at regular intervals and when the network
topology changes. These RIP packets contain information about the networks that the devices can reach,
as well as the number of routers or gateways that a packet must travel through to reach the destination
address. RIP generates more traffic than OSPF, but is easier to configure.
RIP has advantages over static routes because the initial configuration is simple, and you do not need to
update the configuration when the topology changes. The disadvantage to RIP is that there is more
network and processing overhead than static routing.
The security appliance supports RIP Version 1 and RIP Version 2.

Enabling and Configuring RIP

You can only enable one RIP routing process on the security appliance. 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 security appliance sends RIP Version 1 updates and accepts RIP Version 1 and
Version 2 updates.
To enable and configure the RIP routing process, perform the following steps:
Start the RIP routing process by entering the following command in global configuration mode:
Step 1
hostname(config): router rip
You enter router configuration mode for the RIP routing process.
Specify the interfaces that will participate in the RIP routing process. Enter the following command for
Step 2
each interface that will participate in the RIP routing process:
hostname(config-router): network network_address
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.
(Optional) Specify the version of RIP used by the security appliance by entering the following command:
Step 3
hostname(config-router): version [1 | 2]
You can override this setting on a per-interface basis.
(Optional) To generate a default route into RIP, enter the following command:
Step 4
hostname(config-router): default-information originate
Step 5 (Optional) To specify an interface to operate in passive mode, enter the following command:
hostname(config-router): passive-interface [default | if_name]
