634BTuning and optimizing RIP networks
1359BConfiguration 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.
1360BConfiguring RIP timers
You can change the RIP network convergence speed by adjusting RIP timers. Based on network
performance, configure identical RIP timer settings to avoid unnecessary traffic or route flapping.
To configure RIP timers:

121. Enter system view.

123. Configure RIP timers.
timers { garbage-collect
garbage-collect-value | suppress
suppress-value | timeout
timeout-value | update
update-value } *
Optional.
By default:
• The update timer is 30s.
• The timeout timer is 180s.
• The suppress timer is 120s.
• The garbage-collect timer is 120s.
1361BConfiguring 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.
1. 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.
On NBMA networks such as FR and X.25 where multiple VCs are configured on the primary and
secondary interfaces, disable split horizon to ensure correct route advertisement. For more
information, see Layer 2—WAN Configuration Guide.
Disabling split horizon on point-to-point links does not take effect.
