By default, RIP route
redistribution is disabled.
This command can redistribute
only active routes. To view active
routes, use the
display ip
routing-table
protocol
command.

(Optional.) Set a default cost
for redistributed routes.

The default setting is 0.
Tuning and optimizing RIP networks
Configuration prerequisites
Before you tune and optimize RIP networks, complete the following tasks:
•
Configure IP addresses for interfaces to ensure IP connectivity between neighboring nodes.
•
Configure basic RIP.
Setting RIP timers
You can change the RIP network convergence speed by adjusting the following RIP timers:
•
Update timer
—Specifies the interval between route updates.
•
Timeout timer
—Specifies the route aging time. If no update for a route is received within the
aging time, the metric of the route is set to 16.
•
Suppress timer
—Specifies how long a RIP route stays in suppressed state. When the metric
of a route is 16, the route enters the suppressed state. A suppressed route can be replaced by
an updated route that is received from the same neighbor before the suppress timer expires
and has a metric less than 16.
•
Garbage-collect timer
—Specifies the interval from when the metric of a route becomes 16 to
when it is deleted from the routing table. RIP advertises the route with a metric of 16. If no
update is announced for that route before the garbage-collect timer expires, the route is deleted
from the routing table.
IMPORTANT:
To avoid unnecessary traffic or route flapping, configure identical RIP timer settings on RIP routers.
