Using l2vpn / l2circuit (Martini tunnel) in *port mode* on the Juniper routers, you can have the circuit between the two Extreme switch ports be completely transparent. > Doses the Extreme switchs must support QinQ to achieve that ? or simply > configure the ports toward the ciscos as access ? The Extreme switches support QinQ, it is called "vman". It is not enough to simply configure the ports towards the Cisco switches as access, you need to explicitly create a vman. You may also want to define the vman Ethertype (the default is *not* 0x8100).
