Configuring A Ipv6 Multicast Route - Dell PowerConnect B-RX Configuration Manual

The administrative distance is a value that the router uses to compare this route with routes from
other route sources that have the same destination. (The router performs this comparison before
placing a route in the IPv6 route table.) This parameter does not apply to routes that are already in
the IPv6 route table. In general, a low administrative distance indicates a preferred route. By
default, static routes take precedence over routes learned by routing protocols. If you want a
dynamic route to be chosen over a static route, you can configure the static route with a higher
administrative distance than the dynamic route.

Configuring a IPv6 multicast route

IPv6 multicast routes allow you to control the network path used by multicast traffic. Static
multicast routes are especially useful when the unicast and multicast topologies of a network are
different. You can avoid the need to make the topologies similar by instead configuring static
multicast routes.
NOTE
This feature is not supported for DVMRP.
You can configure more than one static IPv6 multicast route. The BigIron RX always uses the most
specific route that matches a multicast source address. Thus, if you want to configure a multicast
static route for a specific multicast source and also configure another multicast static route for all
other sources, you can configure two static routes.
To configure a IPv6 mroute for a destination network with the prefix 8eff::0/32, a next-hop gateway
with the global address 4fee:2343:0:ee44::1, and an administrative distance of 110, enter the
following command.
BigIron RX(config)# ipv6 mroute 8eff::0/32 4fee:2343:0:ee44::1
Syntax: ipv6 mroute <dest-ipv6-prefix>/<prefix-length> <next-hop-ipv6-address>
Syntax: ipv6 mroute <ipv6-addr> interface ethernet <slot>/<portnum> | ve <num> | tunnel
The <ipv6-addr> command specifies the next-hop IP address.
NOTE
In IPv6 multicasting, a route is handled in terms of its source, rather than its destination.
You can use the ethernet <slot>/<portnum> parameter to specify a physical port or the ve <num>
parameter to specify a virtual interface.
NOTE
The ethernet <slot>/<portnum> parameter does not apply to PIM SM.
The next-hop-enable-default parameter sets the default route to resolve the static route nexthop.
The next-hop-recursion parameter sets the static route to resolve the static route nexthop.
The distance <num> parameter sets the administrative distance for the route. When comparing
multiple paths for a route, the BigIron RX prefers the path with the lower administrative distance.
