An Ethernet Routing Switch (ERS) 5300 has been used in a new multicast design. Five Ethernet switches are connected to the ERS 5300 on the same VLAN. Since all of the hosts are on the same shared media LAN, the ERS 5300 will suppress each forwarding report within the VLAN.
Which advantage does using Internet Group Management Protocol (IGMP) snooping with the ERS 5300 and Ethernet Switches offer?
A.Fast Leave functionality is suppressed.
B.It allows for pruning of ports where no IGMP host report has been received.
C.Multicast MAC address floods to all ports on the VLAN.
