Rip Network Adjustment And Optimization - 3Com 4500 PWR 26-Port Configuration Manual

RIP Network Adjustment and Optimization

In some special network environments, some RIP features need to be configured and RIP network
performance needs to be adjusted and optimized. By performing the configuration mentioned in this
section, the following can be implemented:
Changing the convergence speed of RIP network by adjusting RIP timers;
Avoiding routing loops by configuring split horizon;
Packet validation in network environments with high security requirements, and
Configuring RIP to unicast RIP messages on interfaces with special requirements.
Configuration Prerequisites
Before adjusting RIP, perform the following tasks:
Configuring the network layer addresses of interfaces so that adjacent nodes are reachable to
each other at the network layer
Configuring basic RIP functions
Configuration Tasks
Configuring RIP timers
Follow these steps to configure RIP timers:
To do...
Enter system view
Enter RIP view
Set the RIP timers
When configuring the values of RIP timers, you should take network performance into consideration
and perform consistent configuration on all routers running RIP to avoid unnecessary network traffic
and network route oscillation.
Configuring split horizon
Follow these steps to configure split horizon:
To do...
Enter system view
Enter interface view
Enable split horizon
Use the command...
system-view
rip
timers { update
update-timer | timeout
timeout-timer } *
Use the command...
system-view
interface interface-type
interface-number
rip split-horizon
23-8
