Specifying a static group
A multicast group is usually learned when an MLDv1 report is received. You can configure static
group membership without having to receive an MLDv1 report by entering a command such as the
following at the interface level.
Brocade(config-if-e10000-1/1)# ipv6 mld static-group ff0d::1
To configure a static group membership without having to receive an MLDv1 report on a virtual
Ethernet interface, enter the following commands.
Brocade(config)# interface ve 10
Brocade(config-vif-10)# ipv6 mld static-group ff0d::1
Syntax: ipv6 mld static-group multicast-group-address [ethernet port-number [ethernet
port-number | to port-number]*]
Enter the IPv6 multicast group address for the multicast-group-address.
Enter the number of the port that will be included in this static group for the ethernet port-number
parameter. The asterisk (*) in the syntax means that you can enter as many port numbers as you
want to include in the static group. For a virtual routing interface (ve), specify the physical Ethernet
ports on which to add the group address.
Enabling MLD tracking on an interface
When MLD tracking is enabled, a Layer 3 switch tracks all clients that send membership reports.
When a Leave message is received from the last client, the device immediately stops forwarding to
the physical port (without waiting 3 seconds to confirm that no other clients still want the traffic). To
enable MLD tracking on a virtual interface, enter the following commands.
Brocade(config)# interface ve 10
Brocade(config-vif-10)# ipv6 mld tracking
Syntax: ipv6 mld tracking
Setting the version on an interface
You can use this command to set the MLD version (1 or 2) on an interface. You can select the
version of MLD by entering a command such as the following.
Brocade(config)# interface ve 10
Brocade(config-vif-10)# ipv6 mld version 2
Syntax: ipv6 mld version version-number
The version-number variable sets the MLD version on an interface. You can specify 1 or 2 for the
MLD version.The default version is 2.
