Multicast VLAN Registration for IPv4
– 604 –
support common multicast services over a wide part of the network
without having to use any multicast routing protocol.
MVR maintains the user isolation and data security provided by VLAN
segregation by passing only multicast traffic into other VLANs to which the
subscribers belong. Even though common multicast streams are passed
onto different VLAN groups from the MVR VLAN, users in different IEEE
802.1Q or private VLANs cannot exchange any information (except through
upper-level routing services).

General Configuration Guidelines for MVR:
1.
Enable MVR for a domain on the switch, and select the MVR VLAN
(see
"Configuring MVR Domain Settings" on page 607 ).
2.
Create an MVR profile by specifying the multicast groups that will
stream traffic to attached hosts, and assign the profile to an MVR
domain (see "Configuring MVR Group Address Profiles" on
page 608 ).
3.
Set the interfaces that will join the MVR as source ports or receiver
ports (see
"Configuring MVR Interface Status" on page 611 ).
4.
For multicast streams that will run for a long term and be associated
with a stable set of hosts, you can statically bind the multicast
group to the participating interfaces (see "Assigning Static MVR
Multicast Groups to Interfaces" on page 614 ).
◆ Although MVR operates on the underlying mechanism of IGMP
snooping, the two features operate independently of each other. One
can be enabled or disabled without affecting the behavior of the other.
However, if IGMP snooping and MVR are both enabled, MVR reacts only
to join and leave messages from multicast groups configured under
MVR. Join and leave messages from all other multicast groups are
managed by IGMP snooping. Also, note that only IGMP version 2 or 3
