Q-In-Q using M7i and CISCO Switch

People, We have a client with the following situation: v1, v2, v3 -------| Switch | ----------| Switch |----------------| Switch|------------- JUNIPER M7i IQ2E ----- Carrier offers only 3 vlans to the client. But he wants to push some more vlans inside the 3 ones. It is possible to initiate and finish Q-In-Q vlans using a cisco ME switch and a JUNIPER M7i with IQ2E interface ? The following link shows stack configuration. It can be used to do Q-In-Q with this situation ? http://www.juniper.com.lv/techpubs/en_US/junos10.0/information-products/topi... Someone tries to configure it any time ? Thanks a lot, Giuliano
