Tuning And Optimizing Rip Networks; Configuration Prerequisites; Configuring Rip Timers; Configuring Split Horizon And Poison Reverse - HP 830 Series Configuration Manual

Step
2. Enter RIP view.
3. Configure a default metric for
redistributed routes.
4. Redistribute routes from other
routing protocols.

Tuning and optimizing RIP networks

This section describes how to tune and optimize the performance of the RIP network.

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 RIP timers based on network
performance. Each RIP timer must be identical across the network.
To configure RIP timers:
Step
1. Enter system view.
2. Enter RIP view.
3. Configure RIP timers.

Configuring split horizon and poison reverse

The split horizon and poison reverse functions can prevent routing loops. If both split horizon and poison
reverse are configured, only the poison reverse function takes effect.
Enabling split horizon
Split horizon disables RIP from sending routes through the interface where the routes were learned to
prevent routing loops between adjacent routers.

By default:
•
The update timer is 30s.
•
The timeout timer is 180s.
•
The suppress timer is 120s.
•
The garbage-collect timer is 120s.
HP recommends that you not change the
default values of these timers.
