Tuning and optimizing the RIPng network
This section describes how to tune and optimize the performance of the RIPng network, as well as
applications under special network environments. Before tuning and optimizing the RIPng network,
complete the following tasks:
• Configure a network layer address for each interface
• Configure the basic RIPng functions
Configuring RIPng timers
Adjust RIPng timers to optimize the performance of the RIPng network.
Follow these steps to configure RIPng timers:
To do… Use the command… Remarks
Enter system view system-view —
Enter RIPng view ripng [ process-id ] —
Configure RIPng timers
timers { garbage-collect
garbage-collect-value | suppress
suppress-value | timeout
timeout-value | update
update-value } *
Optional.
The RIPng timers have the following defaults:
• 30 seconds for the update timer
• 180 seconds for the timeout timer
• 120 seconds for the suppress timer
• 120 seconds for the garbage-collect timer
NOTE:
When adjusting RIPng timers, consider the network performance, and perform unified configurations on
routers running RIPng to avoid unnecessary network traffic increase 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.
Configure split horizon
The split horizon function disables a route learned from an interface from being advertised through the
same interface to prevent routing loops between neighbors.
Follow these steps to configure split horizon:
To do… Use the command… Remarks

Enable the split horizon function ripng split-horizon
Optional
Enabled by default
