NOTE:
Only active routes can be redistributed. Use the display ip routing-table protocol command to display
route state information.
Tuning and optimizing RIP networks
Complete the following tasks before tuning and optimizing RIP networks:
• Configure network addresses for interfaces, and make neighboring nodes reachable to each other
• Configure RIP basic functions
Configuring RIP timers
You can change the RIP network convergence speed by adjusting RIP timers.
Follow these steps to configure RIP timers:
To do… Use the command… Remarks
Enter system view system-view —
Enter RIP view rip [ process-id ] —
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 need to make RIP timers of RIP routers identical to each other to avoid
unnecessary traffic or route oscillation.
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.
Follow these steps to enable split horizon:
To do… Use the command… Remarks
Enter system view system-view —
Enter interface view

—
Enable split horizon rip split-horizon
Optional
Enabled by default
