Configuring RIP timers

You can change the RIP network convergence speed by adjusting RIP timers. Based on network
performance, make RIP timers of RIP routers identical to each other to avoid unnecessary traffic or route
oscillation.
To configure RIP timers:
Step
1. Enter system view.
2. Enter RIP view.
3. Configure values for RIP
timers.

Configuring split horizon and poison reverse

The split horizon and poison reverse functions can avoid routing loops. If both split horizon and poison
reverse are configured, only the poison reverse function takes effect.
Enabling split horizon
The split horizon function disables an interface from sending routes received from the interface to prevent
routing loops between adjacent routers.
To enable split horizon:
Step
1. Enter system view.
2. Enter interface view.
3. Enable split horizon.
Enabling poison reverse
The poison reverse function allows an interface to advertise the routes received from it, but the metric of
these routes is set to 16, making them unreachable. This can avoid routing loops between neighbors.
To enable poison reverse:
Command
system-view
rip [ process-id ] [ vpn-instance
vpn-instance-name ]
timers { garbage-collect
garbage-collect-value | suppress
suppress-value | timeout
timeout-value | update
