A global RIP setting affects operations on all RIP-enabled interfaces. You configure global
settings in the virtual router.
For instructions for configuring RIP settings on the virtual router and on the interface, see
the Network and Security Manager Online Help.
You can configure the RIP instance parameters displayed in Table 78 on page 323.
Table 78: RIP Instance Parameters
Parameters
RIP Version (ScreenOS 5.1
and later only)
Reject Default Route
Ignore Same Subnet
Checking
Advertising Default Route
Default Metric
Number of Alternate
Routes for Prefix Allowed
(ScreenOS 5.1 and later
only)
Your Action
Select the version of RIP you want to use for this virtual router. When
you configure RIP on the individual interfaces, you can override this
setting.
Select this option to prevent route detour attacks in which a router
injects a default route (0.0.0.0/0) into the routing domain to detour
packets to itself. During a route detour attack, a compromised router
can drop the packets, causing service disruption, or can obtain
sensitive information in the packets before forwarding them. By
default, this option is disabled, meaning RIP accepts any default
routes that are learned in RIP and adds the default route to the routing
table.
Select this option to allow RIP neighbors on different subnets.
Select this option to direct the VR to advertise an active default route
(0.0.0.0/0) in the VR route table to all RIP areas.
Configure the default metric for routes that RIP imports from other
protocols, such as OSPF and BGP. By default, RIP assigns a metric
of 10 to all imported routes.
Configure the maximum number of RIP routes for the same prefix
that RIP can add to the RIP route database. By default, RIP does not
allow alternate routes.
