Customizing 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 the network that covers the network the interface
is attached to, and configure the passive interfaces to prevent that interface from sending RIP.
Additionally, you can specify the version of RIP that is used by the adaptive security appliance for
updates.
In ASDM, you can configure an interface in RIP used by the adaptive security appliance so that all
interfaces on the adaptive security appliance are set to passive RIP mode. The adaptive security
appliance listens for RIP routing broadcasts on all interfaces and uses that information to populate the
routing tables but do not broadcast routing updates. To set specific interfaces to passive RIP, perform the
following steps:
In the main ASDM window, choose Configuration > Device Setup > Routing > RIP > Setup.
Step 1
Check the Enable RIP routing check box.
Step 2
In the Passive Interfaces area, check the check box in the Passive column for those interfaces that you
Step 3
want to have operate in passive mode. The other interfaces will still send and receive RIP broadcasts.
Click Apply.
Step 4
Individual interfaces can be made passive only if the global passive mode is not enabled. Uncheck the
Note
Global Passive check box to make individual interfaces passive using the Passive Interfaces table.
You can override this setting on a per-interface basis in the
"Editing a RIP Interface" section on page
Editing a RIP Interface
In ASDM, the Interface pane allows you to configure interface-specific RIP settings, such as the version
of RIP that the interface sends and receives and the authentication method, if any, that are used for the
RIP broadcasts.
To edit an interface that you have previously set up and configured, perform the following steps:
In the main ASDM window, choose Configuration > Device Setup > Routing > RIP > Setup.
Step 1
Check the Enable RIP routing check box and click Apply.
Step 2
Choose Configuration > Device Setup > Routing > RIP > Interfaces.
Step 3
Click Add or Edit.
Step 4
The Add or Edit RIP Interface Entry dialog box appears and allows you to configure the
interface-specific RIP settings.
(Optional) Choose the following options according to your preferences:
