Q-in-Q question...

[dvtestguy]

Anyone have any expertise with Q-in-Q Stacking VLANS?

I have a 6506 trunked to a 4848 (which supports stacked vlans) and the 6506 trunked to a 7513 NAT'ing to an outside GW.

CE --- 7513 (NAT'ing) --- 6506 --- 4948 --- CE

Like I said earlier, I need to implement this to traverse another hop out to the 7513. My questions are...

1) What do I need to change (if anything) on my trunk between the 6506 and 4948?

2) Do I need to create a tunnel or another trunk between the 6506 and 4948 only allowing the vlan I need to pass through to the 7513?

Please see configs below on both 6506/4948.
