Can I use loopback interface to join igmp group?

Router

interface Loopback0

 ip address 1.1.1.1 255.255.255.255

 ip igmp join-group 239.0.40.1

 ip igmp join-group 239.0.30.1

 ip igmp join-group 239.0.20.1

 ip igmp join-group 239.0.10.1

 ip igmp join-group 239.0.10.1 source 1.1.1.1

I can't see them in mroute table. Other interfaces work fine.

 

thanks !!
