Configuring RIP

RIP Interface Parameters
Table 17.3 lists the interface-level RIP parameters and their default values, and indicates where you can find
configuration information.
.
Update interval How often the router sends route updates to its RIP
neighbors
30 seconds 17-7
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. See Table 17.3 on
page 17-3.
Disabled 17-8
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 permitted
for all neighbors

Table 17.3: RIP Interface Parameters
Parameter Description Default See page...
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.
Disabled 17-4
Metric A numeric cost the router adds to RIP routes learned
on the interface. This parameter applies only to RIP
routes.
1 (one) 17-4
Learning default
routes
Locally overrides the global setting. See Table 17.2
on page 17-2.
Disabled 17-8
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.
