Enabling MLD tracking on an interface

To configure two static groups, starting from ff0d::1, without having to receive an MLDv1 report on a virtual Ethernet interface, enter either this command:

Device(config-if-e1000-1/5)# ipv6 mld static-group ff0d::1 count 2

Or this command:

Device(config-if-e1000-1/5)# ipv6 mld static-group ff0d::1 to ff0d::2

To configure two static groups on virtual ports starting from ff0d::1, enter either this command:

Device(config)# interface ve 10

Device(config-vif-10)# ipv6 mld static-group ff0d::1 count 2 ethernet 1/5 Or this command:

Device(config)# interface ve 10

Device(config-vif-10)# ipv6 mld static-group ff0d::1 to ff0d::2 ethernet 1/5

Syntax: ipv6 mld static-group multicast-group-address[ count count-numberto multicast-group- address ] [ ethernet port-number[ ethernet port-numberto port-number] * ]

Enter the IPv6 multicast group address for the multicast-group-address.

The count-numberrange is 2-256.

Enter the number of the port that will be included in this static group for the ethernet port-numberparameter. 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.

device(config)# interface ve 10 device(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.

device(config)# interface ve 10 device(config-vif-10)# ipv6 mld version 2

Syntax: ipv6 mld version version-number

The version-numbervariable sets the MLD version on an interface. You can specify 1 or 2 for the MLD version.The default version is 2.
