Tuning And Optimizing Rip Networks; Configuration Prerequisites; Setting Rip Timers - HP HPE FlexNetwork 7500 series Configuration Manual

Step
2. Enter RIP view.
3. Redistribute routes from
another routing protocol.
4. (Optional.) Set 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.

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.
To set RIP timers:
Step
1. Enter system view.
2. Enter RIP view.

Remarks
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.
