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 (Routing Information Protocol Next Generation) on specified interfaces.

Syntax Description

vlan-name Specifies an IPv6 configured VLAN (Virtual LAN).
tunnel_name Specifies an IPv6 tunnel.
all Specifies all interfaces.

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
