Igmp Configuration Example - Edge-Core ES4626 User Manual

Switch (Config)#interface vlan 1
Switch(Config-If-Vlan1)#ip igmp static-group 224.1.1.1
20.6.3.10 ip igmp version
Command: ip igmp version <version>
no ip igmp version
Function: Configure IGMP version on interface; the "no ip igmp version" command
restores default value.
Parameter: <version> is IGMP version of configuration, currently supporting version 1, 2
and 3.
Default: Default: version 2.
Command Mode: Interface Configuration Mode
Usage Guide: The command mainly applies to supply upward compatibility of the
different version; it is not communicated between version 1 and version 2, therefore it
must configure to the same version IGMP in the same network. When other routers which
are not upgraded to IGMPv3 on interface-connected subnet need to join member identity
collection of subnet IGMP together, the interface is configured to corresponding version.
Example: Configure IGMP on interface to version 1.
Switch (Config)#interface vlan 1
Switch(Config-If-Vlan1)#ip igmp version 3
