I always tunneled customer vlans between sites doing an access port for the service vlan (access vlan XXX and mode dot1q-tunnel) and in the connected switch a trunk port as usual.
What I tried to do is selective q-in-q but seems I cant do multiple s-vlan with the same c-vlans.
Basically what I need is:
s-vlan 10 transport 100,200,300,400 c-vlans
s-vlan 20 transport 100,200,300,400 c-vlans
s-vlan 30 transport 100,200,300,400 c-vlans
All in the same trunk port from the provider.
It is possible in the cat6504e or in the nexus or I need something else?
Any example or suggestion is welcome.
