So here is my question. I helped to create this network for a client utilizing a trunked VLAN (QinQ) that connects into a Hybrid L2/L3 port. The client is concerned that VLANs will be bandwidth intensive because they will advertise to all devices (ports) on the receiving end of the hybrid port. Another way to put it is the client thinks that each VLAN will advertise to all VLANs on the network thereby increasing the thruput to that port and increasing the congestion unnecessarily (even if the packet is ultimately dropped).
My intention is to have each VLAN speak only to its reciprocating VLAN making it so that each connection maximizes its available bandwidth. Does this make sense and if not can you please elaborate. Thanks!
