24.2.2 Configuring IGMP Parameter
There is no explicit command to enable IGMP, which is always combined with PIM-SM. When
PIM-SM is enabled on an interface, IGMP will be enabled automatically on this interface, vice
versa. But notice, before IGMP can work, IP Multicast-routing must be enabled globally firstly.
Enable IGMP
DUT>enable
Enter Privilege Exec mode
DUT#configure terminal
Enter Configuration mode
DUT(config)#ip multicast-routing
Enable IP Multicast routing globally
DUT(config)#interface eth-0-1
Enter interface eth-0-1
DUT(config-if)#no switchport
Change eth-0-1 as routed port
DUT(config-if)#ip address 10.10.10.10/24
Set the interface IP address
DUT(config-if)#ip pim sparse-mode
Enable ip pim sparse mode
Configuring IGMP interface parameters
DUT>enable
Enter Privilege Exec mode
DUT#configure terminal
Enter Configuration mode
DUT(config)#interface eth-0-1
Enter interface eth-0-1
DUT(config-if)#ip igmp version 2
Set igmp version
DUT(config-if)#ip igmp query-interval 120
Set igmp query interval
DUT(config-if)#ip igmp query-max-response-time 12
Set igmp query max response time
DUT(config-if)#ip igmp robustness-variable 3
Set igmp robustness value
DUT(config-if)#ip igmp last-member-query-count 3
Set igmp last member query count
DUT(config-if)#ip igmp last-member-query-interval 2000

Limit Max IGMP Group number
The limit can be configured globally or per interface
DUT>enable
Enter Privilege Exec mode
DUT#configure terminal
Enter Configuration mode
DUT(config)#ip igmp limit 2000
Set global max igmp group number
DUT(config)#interface eth-0-1
Enter interface eth-0-1
DUT(config-if)#ip igmp limit 1000
