Configuring RIPng timers
You can adjust RIPng timers to optimize the performance of the RIPng network. 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.
To configure RIPng timers:
Ste
p
Command Remarks
1. Enter system view.
system-view N/A
2. Enter RIPng view.
ripng [ process-id ] N/A
3. 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
Configuring split horizon and poison reverse
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.
HP recommends enabling split horizon to prevent routing loops.
To configure split horizon:

Command Remarks
1. Enter system view. system-view N/A
2. Enter interface view.
interface interface-type
interface-number
N/A
3. Enable the split horizon
function.
ripng split-horizon
Optional.
Enabled by default.
Configuring the poison reverse function
The poison reverse function enables a route learned from an interface to be advertised through the
interface. However, the metric of the route is set to 16, which causes the route to be unreachable.
To configure poison reverse:
