Required
No redistribution is configured by

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:

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, 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.
