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

HP recommends enabling split horizon to prevent routing loops.
To configure split horizon:

Optional.
Enabled by default.
Configuring poison reverse
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 means the route is unreachable.
