The Cisco could have one or more VLANs configured, and we need to get all of these VLANs in to a single interface in our T1. If you only have a single VLAN, then a Trunk port is not required, but in some way it would be a good practice to use a trunk port, as if you needed to add VLANs later, half your work is already done. |

| - | First of all, I would like to outline what I am trying to achieve. Look at the diagram below. | ||

| - | There are two sets of receivers (so consider two sets of multicast) coming from different head-ends. To keep the traffic separate, lets consider that the ports connected to the receivers on the left are all in VLAN A, and the receivers on the right are in VLAN B, as show below. | ||

| - | VLAN C is on another switch where our destination equipment is located. The link between the two Cisco switches is our Trunk. | ||

| - | The reason we are using a Trunk is that a single port (interface) can only carry traffic from a single VLAN, because an interface can only exist in one VLAN. So if you have multiple VLANs that you wish to carry from one switch to another, you need to use a Trunk. A Trunk can carry the traffic from mulitple VLANs. | ||
