Configuring Ripng Timers; Configuring Split Horizon And Poison Reverse - HP MSR2000 series Configuration Manual

Configuring RIPng timers

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:
Step
1. Enter system view.
2. Enter RIPng view.
3. Configure RIPng
timers.

Configuring split horizon and poison reverse

If both split horizon and poison reverse are configured, only the poison reverse function takes effect.
Configuring 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:
Step
1. Enter system view.
2. Enter interface view.
3. Enable the split horizon
function.
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 (unreachable).
To configure poison reverse:
Step
1. Enter system view.
2. Enter interface view.
