72. Display the records in the multicast communication routing table:

 

Dallasr1>show ip mroute [group-name|group-address][scoure][summary][count][active kbps]

 

73. To record all IP multicast packets accepted and sent by a router :

 

Dallasr1> #debug ip mpacket [detail] [access-list][group]

 

74. To configure CGMP on the CISCO router :
