ip igmp snoopi ng vlan mr outer
To statically configure an Layer 2 interface as a multicast router interface for a VLAN, use the
ip igmp snooping vlan mroute r command. To remove the configuration, use the no form of this
command .
ip igmp snooping vlan vla n-id mrouter {interface {{fastethe rnet slot/por t} | {gigabite thernet
slot/port} | {tengigabitethernet slot/port} | {po rt-c ha nne l num ber}} |
{learn {cgmp | pim-dvmrp}}
no ip igmp snooping vlan vlan-id mrouter {interface {{fastethernet slot/port} | {gigabitethernet
slot/port} | {tengigabitethernet slot/port} | {po rt-c ha nne l num ber}} |
{learn {cgmp | pim-dvmrp}}
Syntax Description
Defaults Multicast switch snooping PIM-DVMRP packets are specified.
Command Modes Interface configur ation mode
Usage Guidelines You enter this command in VLAN interface configuration mode only.
The interface to the switch must be in the V LAN where you are entering the command. It mu st be both
administratively up and line proto col up.
The CGMP learning method can decrease control traffic.
The learning method that you configur e is saved in NVRAM.
The static connections to multicast interfaces are supported only on switch interfaces.
Examples This example shows how to specify the next-hop interface to a multicast switch:
Switch(config-if)# ip igmp snooping 400 mrouter interface fastethernet 5/6
Switch(config-if)#
vlan vlan-id Specifies the VLAN ID number to use in the command; valid values are
from 1 to 4094.
interface Specifies the next-hop interface to a multicast switch.
fastethernet slot/port Specifies the Fast Ethernet interface; number of the slot and port.
gigabitethernet slo t/port Specifies the Gigabit Ethernet interface; number of the slot and port.
tengigabitethernet
slot/port
Specifies the 10-Gigabit Ethernet interface; number of the slot and port.
port-channel number Po rt-channel number ; valid values are from 1 to 64.
learn Specifies the multicast switch learning method.
cgmp Specifies the multicast switch snooping CGMP packets.
pim-dvmrp Specifies the multicast switch snooping PIM-DVMRP packets.
