Chapter 2 Cisco ME 3400 Ethernet Access Switch Cisco IOS Commands
ip igmp snooping vlan mrouter
ip igmp snooping vlan mrouter
Use the ip igmp snooping vlan vlan-id mrouter global configuration command to add a multicast router
port or to configure the multicast learning method. Use the no form of this command to return to the
default settings.
ip igmp snooping vlan vlan-id mrouter {interface interface-id | learn pim-dvmrp}
no ip igmp snooping vlan vlan-id mrouter {interface interface-id | learn pim-dvmrp}
Syntax Description
Defaults By default, there are no multicast router ports.
The default learning method is pim-dvmrp—to snoop IGMP queries and PIM-DVMRP packets.
Command Modes Global configuration
Command History
Usage Guidelines VLAN IDs 1002 to 1005 are reserved for Token Ring and FDDI VLANs and cannot be used in IGMP
snooping.
The configuration is saved in NVRAM.
Examples This example shows how to configure a port as a multicast router port:
Switch(config)# ip igmp snooping vlan 1 mrouter interface gigabitethernet0/2
You can verify your settings by entering the show ip igmp snooping privileged EXEC command.
vlan-id Enable IGMP snooping, and add the port in the specified VLAN as the
multicast router port. The range is 1 to 1001 and 1006 to 4094.
interface interface-id Specify the next-hop interface to the multicast router. Valid interfaces are
physical interfaces and port channels. The port-channel range is 1 to 48.
learn pim-dvmrp Specify the multicast router learning method. The only learning method
supported on the Cisco ME switch is pim-dvmrp, which sets the switch to
learn multicast router ports by snooping on IGMP queries and
Protocol-Independent Multicast-Distance Vector Multicast Routing Protocol
(PIM-DVMRP) packets.
