Is it possible to connect a 857 ADSL router to a 3750 L3 switch with QinQ
tagging. Thank you.

Yes, they both have ethernet ports that you can run a cable inbetween.

Maybe there's some better question in there? More info would be better.

Hmmmm. 857 only supports one VLAN and cannot
run Advanced IP Services Feature Set.

Might work but I guess it wont.

877 supports 1 to 4 VLANS. No idea at all if it might do
QinQ tunneling. I kind of thought that the "switch" hardware was quite
basic.

www.cisco.com/go/fn -- Feature Navigator might assist.
May not be available for public access. Not sure.

QinQ isn't supported in 857, that's why i use a 3750 to connect to Metro
Ethernet. If i configure default VLAN 1 in an access port in 3750 and VLAN
100 (for example) for a trunk port and the S-VLAN, would it work, having
only this client on the 3750?
Thank you very much.

-------------------------------------

Rephrasing my question, the problem is if i can configure QinQ with VLAN 1
(as the C-VLAN) and VLAN 100 (as the S-VLAN) in a 3750 that connects to a
857 router that doesn't support VLANs.
If anyone knows, could you please help in this.
Thank you!
