I don't think so. A trunk type is just a tag type and has nothing to do with
the traffic inside it. When you configure VLAN's, you split up your network
into broadcast domains. So I think that you will have less traffic on a
trunk than you have without the trunks. Beware that when you (in the router)
bridge between the VLAN's, the amount of traffic will be increased because a
broadcast on VLAN 1 will also appear in VLAN 2.....so this broadcast will be
twice inside the trunk.
I hope this helps,
Gerwin
