Prerequisites 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
You can adjust RIPng timers to optimize the performance of the RIPng network.
Follow these steps to configure RIPng timers:
n
When adjusting RIPng timers, you should consider the network performance and
perform unified configurations on routers running RIPng to avoid unnecessary
network traffic.
Configuring Split
Horizon
The split horizon function disables a route learned from an interface from being
advertised via the interface to prevent routing loops between neighbors.
Follow these steps to configure the split horizon:
To do... Use the command... Remarks
Enter system view system-view -
Enter RIPng view ripng [ process-id ] -
Configure RIPng timers timers { garbage-collect

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
