Hi

I am search a solution for this project:


Cisco 7301 connected to a Cisco 3750 "A"  by a Fiber Gig port. Port is in
trunk
     C7301 <==> C3750 port gig 0/24


The cisco 3750 "A" is connecter in trunk to a carrier by the Gig 0/23.

The carrier supply 4 ports:
    1 Central Port connected to C3750 "A"
    1 Port connected to C3750 "B"
    1 Port connected to C3750 "C"
    1 Port connected to C3750 "D"

And on each, he supply one vlan
      Vlan 100: From C3750"A" to Cisco 3750 "B"
      Vlan 101: From C3750"A" to Cisco 3750 "C"
      Vlan 102: From C3750"A" to Cisco 3750 "D"


I want use QinQ for:
     Cisco 7301 use vlan 500 to 600 for going on 3750 "B"
     Cisco 7301 use vlan 700 to 800 for going on 3750 "C"
     Cisco 7301 use vlan 900 to 1000 for going on 3750 "D"



Sample:

    C7301 ge0/1.500 => trunk => C3750 "A" <== Dot1q Tunnel into Vlan 100
==> C3750 "B" => Trunk => C2821 ge1/1.500

    C7301 ge0/1.750 => trunk => C3750 "A" <== Dot1q Tunnel into Vlan 101
==> C3750 "C" => Trunk => C1841 ge1/1.750

    C7301 ge0/1.950 => trunk => C3750 "A" <== Dot1q Tunnel into Vlan 102
==> C3750 "D" => Trunk => C2811 ge1/1.950



It's possible ?

Olivier
