ip igmp snooping vlan mrouter interface
Routing interface is a port through which a multicast device is directly connected to a multicast
neighboring device. To configure a multicast routing interface, execute the ip igmp snooping vlan
mrouter interface command in the global configuration mode. The no form of this command is used to
delete a routing interface.
ip igmp snooping vlan vid mrouter interface interface-id
no ip igmp snooping vlan vid mrouter interface interface-id
VLAN ID of a routing interface
Global configuration mode.
When the source port check function is enabled, only the multicast
flows from the routing interface are forwarded, and other flows will be
discarded.
The following example demonstrates how to configure a multicast
routing interface on the equipment:
Ruijie(config)# ip igmp snooping vlan 1 mrout erinterface
fastEthernet 0/1
ip igmp snooping
source-check port
Enable the multicast
source port check function.
ip igmp snooping vlan mrouter learn pim-dvmrp
To configure a device to listen to the IGMP query/dvmrp or PIM packets dynamically in order to
automatically identify a routing interface, execute the ip igmp snooping vlan mrouter learn command
in the global configuration mode. The no form of this command is used to disable the dynamic learning.
ip igmp snooping vlan vid mrouter learn pim-dvmrp
no ip igmp snooping vlan vid mrouter learn pim-dvmrp
