MVR for IPv6
– 759 –
Command Usage
◆ A port configured as an MVR6 receiver or source port can join or leave multicast
groups configured under MVR6. A port which is not configured as an MVR6
receiver or source port can use MLD snooping to join or leave multicast groups
using the standard rules for multicast filtering (see “MLD Snooping” on
page 702).
◆ Receiver ports can belong to different VLANs, but should not be configured as a
member of the MVR6 VLAN. MLD snooping can be used to allow a receiver port
to dynamically join or leave multicast groups not sourced through the MVR6
VLAN. Also, note that VLAN membership for MVR6 receiver ports cannot be set
to access mode (see the switchport mode command).
◆ One or more interfaces may be configured as MVR6 source ports. A source port
is able to both receive and send data for multicast groups which it has joined
through the MVR6 protocol or which have been assigned through the mvr6
vlan group command.
All source ports must belong to the MVR6 VLAN.
Subscribers should not be directly connected to source ports.
◆ The same port cannot be configured as a source port in one MVR6 domain and
as a receiver port in another domain.
Example
The following configures one source port and several receiver ports on the switch.
Console(config)#interface ethernet 1/5
Console(config-if)#mvr6 domain 1 type source
Console(config-if)#exit
Console(config)#interface ethernet 1/6
Console(config-if)#mvr6 domain 1 type receiver
Console(config-if)#exit
Console(config)#interface ethernet 1/7
Console(config-if)#mvr6 domain 1 type receiver
Console(config-if)#
mvr6 vlan group This command statically binds a multicast group to a port which will receive long-
term multicast streams associated with a stable set of hosts. Use the no form to
restore the default settings.
