Configuring a IPv6 static multicast route
A metric is a value that the Brocade device uses when comparing this route to other static routes in
the IPv6 static route table that have the same destination. The metric applies only to routes that
the device has already placed in the IPv6 static route table.
The administrative distance is a value that the Brocade device uses to compare this route with
routes from other route sources that have the same destination. (The device 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 static 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 Brocade device by default uses
the most specific route that matches a multicast source address. You can also specify route
preference using the route-preference command as described in the Configuring IP Multicast
Protocols chapter in the Multi-Service IronWare IP Multicast Configuration Guide. 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 2001:db8::0/32, a next-hop
gateway with the global address 2001:db8:0:ee44::1, and an administrative distance of 110, enter
the following command.
Brocade(config)# ipv6 mroute 2001:db8::0/32 2001:db8:0:ee44::1 distance 110
Syntax: [no] ipv6 mroute dest-ipv6-prefix/prefix-length next-hop-ipv6-address
next-hop-enable-default next-hop-recursion [metric] [distance number] [tag number]
Syntax: [no] ipv6 mroute ipv6-addr interface ethernet slot/portnum | ve num | tunnel num
[distance num] [tag number]
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.
Tag number This parameter specifies the tag
value of the route. The possible values are
0 - 4294967295.
The default is 0.
The route’s administrative
distance. You must specify the distance
keyword and any numerical value. Optional for all static IPv6 routes. (The
default administrative distance is 1.)
