Rip Interface Parameters - Foundry Networks FESX Manual

Parameter Description
Update interval How often the router sends route updates to its RIP
neighbors
Learning default The router can learn default routes from its RIP
routes neighbors.
Note: You also can enable or disable this parameter
on an individual interface basis. See Table 17.3 on
page 17-3.
Advertising and The Layer 3 Switch learns and advertises RIP routes
learning with with all its neighbors by default. You can prevent the
specific Layer 3 Switch from advertising routes to specific
neighbors neighbors or learning routes from specific neighbors.

RIP Interface Parameters

Table 17.3 lists the interface-level RIP parameters and their default values, and indicates where you can find
configuration information.
.
Parameter Description
RIP state and The state of the protocol and the version that is
version 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 Locally overrides the global setting. See Table 17.2
routes on page 17-2.
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.
