RIP interface parameters
Table 172 lists the interface-level RIP parameters and their default values, and indicates where you
can find configuration information.
.
Learning
default routes
The router can learn default routes from its RIP neighbors.
NOTE: You also can enable or disable this parameter on an
individual interface basis. Refer to Table 172 on
page 909.
Disabled page 915
Advertising
and learning
with specific
neighbors
The Layer 3 Switch learns and advertises RIP routes with all its
neighbors by default. You can prevent the Layer 3 Switch from
advertising routes to specific neighbors or learning routes from
specific neighbors.
Learning and
advertising

all neighbors

TABLE 172 RIP interface parameters
Parameter Description Default Reference
RIP state and
version
The state of the protocol and the version that is
supported on the interface. The version can be
one of the following:
• Version 1 only
• Version 2 only
• Version 1, but also compatible with version 2
NOTE: You also must enable RIP globally.

Metric A numeric cost the router adds to RIP routes
learned on the interface. This parameter applies
only to RIP routes.

Learning default
routes
Locally overrides the global setting. Refer to
Table 171 on page 908.
Disabled page 915
Loop prevention The method a router uses to prevent routing loops
caused by advertising a route on the same
interface as the one on which the router learned
the route.
• Split horizon – The router does not advertise
a route on the same interface as the one on
which the router learned the route.
• Poison reverse – The router assigns a cost of
16 (“infinite” or “unreachable”) to a route
before advertising it on the same interface
as the one on which the router learned the
route.
Poison reverse
NOTE: Enabling split
horizon disables
poison reverse on
the interface.

Advertising and
learning specific
routes
You can control the routes that a Layer 3 Switch
learns or advertises.
The Layer 3 Switch learns
and advertises all RIP
routes on all interfaces.
