31-5 ip igmp snooping mrouter
This command is used to configure the specified interface(s) as the multicast router ports or as forbidden
to be multicast router ports on the Switch. Use the no form of this command to remove the interface(s)
from router ports or forbidden multicast router ports.
ip igmp snooping mrouter {interface INTERFACE-ID [,|-] | forbidden interface INTERFACE-ID [,|-]}
no ip igmp snooping mrouter {interface INTERFACE-ID [,|-] | forbidden interface INTERFACE-ID
[,|-]}
Parameters
interface
Specifies a static multicast router port.
forbidden interface
Specifies a port that cannot be multicast router port.
INTERFACE-ID
(Optional) Specifies an interface or an interface list. The interface can
be a physical interface or a port-channel.
,
(Optional) Specifies a series of interfaces, or a separate a range of
interfaces from a previous range. No space is allowed before and after
the comma.
-
(Optional) Specifies a range of interfaces. No space is allowed before
and after the hyphen.
Default
No IGMP snooping multicast router port is configured.
Auto-learning is enabled.
Command Mode
Interface Configuration Mode.
Command Default Level
Level: 12.
Usage Guideline
This command is only available for VLAN interface configuration. To specify a multicast router port, the
valid interface can be a physical port or a port-channel. The specified multicast router port must be
member port of the configured VLAN. A multicast router port can be either dynamic learned or statically
configured. With the dynamic learning, the IGMP snooping entity will learn IGMP, PIM, or DVMRP packet
to identify a multicast router port.
Example
This example shows how to add an IGMP snooping static multicast router port for VLAN 1.
Switch# configure terminal
Switch(config)# vlan 1
Switch(config-vlan)# ip igmp snooping mrouter interface eth4/0/1
Switch(config-vlan)#
