Enable Ripng Poisonreverse - Extreme Networks ExtremeWare XOS Command Reference Manual

enable ripng poisonreverse

enable ripng poisonreverse {vlan <vlan-name> | tunnel <tunnel_name> | [vlan
| tunnel] all}
Description
Enables the split horizon with poison reverse algorithm for RIPng on specified interfaces.
Syntax Description
vlan-name
tunnel-name
all
Default
Enabled.
Usage Guidelines
Used with split horizon, poison reverse is a scheme for eliminating the possibility of loops in the routed
topology. In this case, a router advertises a route over the same interface that supplied the route, but the
route uses a hop count of 16, defining it as unreachable.
If both split horizon and poison reverse are enabled, poison reverse takes precedence.
Example
The following command enables split horizon with poison reverse for RIPng on all IPv6 interfaces in
the virtual router:
enable ripng poisonreverse
The following command enables split horizon with poison reverse for all the IPv6 configured VLANs in
the virtual router:
enable ripng poisonreverse vlan all
