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.
