Tuning And Optimizing Rip Networks; Configuration Prerequisites; Configuring Rip Timers - HP 6125XLG Configuration Manual

Step
1. Enter system view.
2. Enter RIP view.
3. Redistribute routes from
another routing protocol.
4. (Optional.) Configure a
default cost for redistributed
routes.

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.
•

Configuring 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.
To configure RIP timers:
Step
1. Enter system view.

N/A
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.
The default setting is 0.
