MVR for IPv4

[no] mvr [domain domain-id] immediate-leave [by-host-ip]

domain-id - An independent multicast domain. (Range: 1-5)

by-host-ip - Specifies that the member port will be deleted only

when there are no hosts joining this group.

Interface Configuration (Ethernet, Port Channel)

Immediate leave applies only to receiver ports. When enabled, the

receiver port is immediately removed from the multicast group

identified in the leave message. When immediate leave is disabled, the

switch follows the standard rules by sending a group-specific query to

the receiver port and waiting for a response to determine if there are

any remaining subscribers for that multicast group before removing the

port from the group list.

If the "by-host-ip" option is used, the router/querier will not send out a

group-specific query when an IGMPv2/v3 leave message is received

(the same as it would without this option having been used). Instead of

immediately deleting that group, it will look up the record, and only

delete the group if there are no other subscribers for it on the member

port. Only when all hosts on that port leave the group will the member

port be deleted.

Using immediate leave can speed up leave latency, but should only be

enabled on a port attached to only one multicast subscriber to avoid

disrupting services to other group members attached to the same

Immediate leave does not apply to multicast groups which have been

statically assigned to a port with the

The following enables immediate leave on a receiver port.

Console(config)#interface ethernet 1/5

Console(config-if)#mvr domain 1 immediate-leave

Console(config-if)#

This command configures an interface as an MVR receiver or source port.
