As shown above, the multicast group 224.1.1.1 has been registered on Switch A, with the dynamic
router port Ethernet 1/0/1 and dynamic member ports Ethernet 1/0/3 and Ethernet 1/0/4. This means
that Host A and Host B have joined the multicast group 224.1.1.1.

multicast source. A Layer 2 switch, Switch B forwards the multicast data to the end users Host A and
Host B.

Networking description
The interface IP address of VLAN 20 is 168.10.1.1. Ethernet
1/0/1 is connected to the workstation and belongs to VLAN
20.
The interface IP address of VLAN 10 is 168.10.2.1. Ethernet
1/0/10 belongs to VLAN 10. Ethernet 1/0/10 is connected to
Switch B.
VLAN 2 contains Ethernet 1/0/1 and VLAN 3 contains
Ethernet 1/0/2.
The default VLANs of Ethernet 1/0/1 and Ethernet 1/0/2
are VLAN 2 and VLAN 3 respectively.
VLAN 10 contains Ethernet 1/0/10, Ethernet 1/0/1, and
Ethernet 1/0/2. Ethernet 1/0/10 is connected to Switch A.
VLAN 10 is a multicast VLAN.
Ethernet 1/0/1 sends untagged packets for VLAN 2 and
VLAN 10.
Ethernet 1/0/2 sends untagged packets for VLAN 3 and
VLAN 10.
