10.5 RIPng Commands
RIPng is intended to allow routers to exchange information for computing routes through an IPv6-based
network. RIPng is a distance vector protocol. RIPng should be implemented only in routers. Any router
that uses RIPng is assumed to have interfaces to one or more networks
, otherwise it isn’t really a router.
These are referred to as its directly-connected networks. The protocol relies on access to certain
information about each of these networks, the most important of which is its metric. The RIPng metric of
a network is an integer between 1 and 15, inclusive. It is set in some manner not specified in this
protocol; however, given the maximum path limit of 15, a value of 1 is usually used. Implementations
should allow the system administrator to set the metric of each network. In addition to the metric, each
network will have an IPv6 destination address prefix and prefix length associated with it. These are to be
set by the system administrator in a manner not specified in this protocol.

This command displays information relevant to the RIPng router
Syntax
show ipv6 rip

Privileged Exec

RIPng Admin Mode: Select enable or disable from the pulldown menu. If you select enable RIPng
will be enabled for the switch. The default is disabled.
Split Horizon Mode: Select none, simple or poison reverse from the pulldown menu. Split horizon is
a technique for avoiding problems caused by including routes in updates sent to the router from
which the route was originally learned. The options are: None - no special processing for this case.
Simple - a route will not be included in updates sent to the router from which it was learned.
Poisoned reverse - a route will be included in updates sent to the router from which it was learned,
but the metric will be set to infinity. The default is simple.
Default Metric: Sets a default for the metric of redistributed routes. This field displays the default
metric if one has already been set or blank if not configured earlier. The valid values are (1 to 15).
Default Route Advertise: The default route.
Distance: Configured value.
Update Time: Configured value.
Garbage Time: Configured value.
