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.
3.
Enable the poison reverse
function.
