MVR Interoperation with Other Features

on the VLAN, the port is removed immediately; otherwise, an IGMP query is sent to the group to determine
whether other hosts are present on the port.

MVR and IGMP Snooping
Although MVR operates on the underlying mechanism of IGMP snooping, the two features operate
independently of each other. One feature can be enabled or disabled without affecting the operation of the
other feature. If IGMP snooping is disabled globally or on a VLAN, and if MVR is enabled on the VLAN,
IGMP snooping is internally enabled on the VLAN. Joins received for MVR groups on non-MVR receiver
ports, or joins received for non-MVR groups on MVR receiver ports, are processed by IGMP snooping.
MVR and vPC
• As with IGMP snooping, IGMP control messages received by virtual port channel (vPC) peer switches
• MVR configuration must be consistent between the peers.
• The no ip igmp snooping mrouter vpc-peer-link command applies to MVR. With this command,
• The show mvr member command shows the multicast group on the vPC peer switch. However, the

are exchanged between the peers, allowing synchronization of MVR group information.
multicast traffic is not sent over to a peer link for the source VLAN and receiver VLAN unless there is
an orphan port in the VLAN.
vPC peer switch does not show the multicast groups if it does not receive the IGMP membership report
of the groups.
