A Customer has a layer2 switch as the edge device, connected directly to the Metro Ethernet Provider (LAN extesnion). The Metro Network is connected to an ATM Cloud which in turn connected to another Metro area.
My question is how the customer will configure his VLAN on the edge switch .. Can he configure any vlan ID or he has to comply/align with the VLAN mapped on the ATM VC by the provider. Please advise as it is really confusing me. Thanks
If the the proivder is not using QinQ then let us take an example.
Assuming the proivder is using vlan 202 mapped to the ATM VC so he has to use a subnet that can accomadate the customer hosts /24 or /26 ?? and then the customer will use the same vlan id 202 for his hosts and also has to a gateway ip address in the same subnet say 192.168.202.1 ( can that be his router at the other end of the ATM VC.. )
