Thanks for the input all.
Another question for the group, what about
an EoMPLS environment that is a hub and spoke topology where several of the
remote locations are attached to the same PE as the hub location? We can’t
do an xconnect since that remote to hub traffic never leaves the PE into the
MPLS cloud. Do I need to provision a second circuit between the PE and the hub
location CE and just do pure layer 2 transport between those remotes that
attach to the same PE as the hub location?

Ethernet over MPLS with Different Custo mers using the s ame VLAN
the switch ports can be trunk ports no
problem. What you have to do as an SP is to allocate a single vlan for
that port i.e. something like
switchport access vlan 100
You then take that vlan 100 and
"throw" it across your mpls network which then gets stripped off at
the end switch.

Thinking out loud.....since these are
trunk ports, once the MPLS label is prepended to the packet at the PE, the
duplicate customer VLANs shouldn't matter anyway since they won't be seen after
they are encapsulated?

One more clarification, the access ports
need to be 802.1q trunk ports.
Thanks again.

Subject: [MPLS-OPS]: Configure
Ethernet over MPLS with Different Customers using the s ame VLAN
Hello Folks,
We are implementing a Metro Ethernet network using
Cisco 6500 series MPLS switches with the core connected with 10GigE cards. This
is a service provider network configured for EoMPLS (Martini Draft) and will
have some customers using the same access VLANs.
With a Layer 2 access configuration, what is the
best configuration to accomplish this? QinQ? We have no problem using unique
VLANs on the PE side but need to ensure that customer access VLANs can overlap
each other on the same PE switch.
Any input is much appreciated.
Thanks.
