Configuring Interfaces for RIP
If you have an interface that you do not want to have participate in RIP routing, but that is attached to a
network that you want advertised, you can configure the network (using the network command) that
includes the network to which the interface is attached, and configure the passive interfaces (using the
passive-interface command) to prevent that interface from using RIP. Additionally, you can specify the
version of RIP that is used by the ASA for updates.
To configure interfaces for RIP, perform the following steps:
Detailed Steps
Configuring the RIP Send and Receive Version on an Interface
You can override the globally-set version of RIP that the ASA uses to send and receive RIP updates on
a per-interface basis.
To configure the RIP version for sending and receiving updates, perform the following steps:
Detailed Steps
Command Purpose
Step 1 router rip
Example:
hostname(config)# router rip
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
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 passive-interface [ default | if_name ]
Example:
hostname(config-router)# passive-interface
[default]
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 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.
Command Purpose
Step 1 interface phy_if
Example:
hostname(config)# interface phy_if
Enters interface configuration mode for the interface that you are
configuring.
Step 2 Do one of the following to send or receive RIP updates on a per-interface basis.
