Hi,

2547bis says

"A customer edge (CE) device provides customer access to the service
provider network over a
data link to one or more provider edge (PE) routers. While the CE device
can be a host or a
Layer 2 switch, typically the CE device is an IP router that establishes an
adjacency with its
directly connected PE routers."

Suppose a customer  has a L2 CE device (switch) & his requirement is that
he has to be accomodated on to the Providers existing BGP/MPLS L3 VPN based
setup with his CE device.


i have heard there is a workaround for such scenarios wherein...a sort of
virtual router that mimics a L3 CE device is created on the PE of the
provider which connects to L2 CE..and the VPN in turn starts from the PE
connecting to this PE.
my question??
need clarity -whether this works and how exactly this will work if it will.

will be thankful to be referred to links that explore such a scenario

Regards,

Devendra Vyas
