Example:
Configure static-group 224.1.1.1 on interface vlan1.
Switch (Config)#interface vlan 1
Switch(Config-If-Vlan1)#ip igmp static-group 224.1.1.1
17.6.3.10 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
17.6.4 IGMP Configuration Example
As shown in the following figure, add the Ethernet ports of Switch A and Switch B to
corresponding vlan, and start PIM-DM on each vlan interface.
Fig 17-4 IGMP Network Topology Diagram
The configuration procedure for SwitchA and SwitchB is as follows:
(1) Configure SwitchA:
Switch(Config)#ip pim multicast-routing
SwitchA
SwitchB
Ethernet1/1
vlan1
Ethernet1/1
vlan1
Ethernet1/2
vlan2
