multicast router ports.
ip igmp snooping {mrouter-designate | mrouter-not-allowed} interface INTERFACE-ID [ , | - ]
no ip igmp snooping {mrouter-designate | mrouter-not-allowed} interface INTERFACE-ID [ , | - ]
Default No IGMP snooping multicast router port is configured.
Command Mode VLAN interface configuration
Usage Guideline The valid interface can be a physical port or a port-channel for the INTERFACE-
ID parameter.
The router member port can be either dynamically learned or statically
configured into an IGMP snooping entity. With dynamic learning, the IGMP
snooping entity will listen to IGMP, PIM, and DVMRP packet to identify whether
the partner device is a multicast router.
To add a multicast router port statically, use the ip igmp snooping mrouter-
designate configuration. On the opposite side, it is also possible to use ip igmp
snooping mrouter-not-allowed to configure those ports that cannot become
multicast router ports even the port has received IP multicast control protocol
message.
The member port of a port channel can not be enabled with the ip igmp
snooping {mrouter-designate | mrouter-not-allowed} command, an error
message is displayed if the designated port is ineligible.
Syntax Description
