3. Configure a default metric for
redistributed routes.
default cost value
Optional.
The default setting is 0.
4. Redistribute routes from other
routing protocols.

| all-processes | allow-ibgp ] [ cost
cost | route-policy

By default, route redistribution is
disabled.
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 RIP timers. Based on network
performance, configure identical RIP timer settings to avoid unnecessary traffic or route flapping.
To configure RIP timers:

Command Remarks
1. Enter system view.
system-view N/A
2. Enter RIP view.
rip [ process-id ] [ vpn-instance

3. 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.
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.
