We're trying to do traffic separation from a server to an X670 to another switch. The server can only use a single VLAN tag, so between it and the X670 we're using GRE tunnels for each traffic type within that single VLAN, and terminating the GRE tunnel on the X670 through the use of multiple secondary IP's assigned to that VLAN. We have this up and working.
Between the X670 and the other switch we want to use different VLAN's for the traffic separation via a single trunked link. So whats the best way of doing this?. Do I just create multiple VLAN's (one per traffic type), assign an IP to each one, and route traffic to that IP address as the next hop, and then add each VLAN to the trunk link?
