Command Remarks
3. Configure values for RIP timers.
timers { garbage-collect
garbage-collect-value | suppress
suppress-value | timeout
timeout-value | update
update-value } *
Optional.
The default update timer,
timeout timer, suppress timer,
and garbage-collect timer are
30s, 180s, 120s and 120s
respectively.
NOTE:
Based on network performance, you must make RIP timers of RIP routers identical to each other to avoid
unnecessary traffic or route oscillation.
Configuring split horizon and poison reverse
NOTE:
If both split horizon and poison reverse are configured, only the poison reverse function takes effect.
The split horizon and poison reverse functions can avoid routing loops.
• Enable 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:

Command Remarks
1. Enter system view. system-view N/A
2. Enter interface view.

N/A
3. Enable split horizon.
rip split-horizon
Optional.
Enabled by default.
NOTE:
Disabling the split horizon function on a point-to-point link does not take effect.
• Enable 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:
