Complete the following steps to verify your configuration:

1. Use the show ip igmp groups command to verify that the receiver has sent its IGMP join membership request for group 239.1.1.20 to R104. 

r104# show ip igmp groups 

IGMP Connected Group Membership

Uptime    Expires   Last Reporter

239.1.1.20

Ethernet0/0

00:00:04  00:02:55  10.2.2.3

2. Use the show ip mroute group-address command to display that when the source 10.1.1.1 starts multicasting packets for the group 

239.1.1.20, R102 installs the (*,239.1.1.20) and (10.1.1.1, 239.1.1.20) entries in the R102 mroute table, as shown below.
