Thanks, James. I understand now. I was reading the doc again and it became
clear.

Assigning a metro tag (802.1q tunneling or Q-in-Q) allows providers to
support customers with overlapping vlan tags. L2 protocol tunneling allows
BPDUs etc to also be tunneled making the provider entirely transparent to
the customer.

Hey Group,
 
I'm trying to understand what the major differences are between the two and
when you would use one over the other. I read the section on the doc cd,
but I don't fully understand it.
 
Thanks,
Danny
