Hi GS

I'm curious about l2protocol-tunnel in a setup similar to a
point-to-multipoint setup as depicted below:

CE-switch -> access circuit -> PE-switch -> MPLS cloud -> PE-switch ->
access circuit -> CE-switch

Between the two PE-switches an EoMPLS tunnel is created, connecting two SVI
interfaces.

The access circuit is a point-to-multipoint system supporting several
different customers. All customers are terminated as a different Vlan, all
sharing the same port in the PE-switch.

My question is, if it is possible to transfer the customer CDP, VTP etc
packages across the MPLS cloud using l2protocol-tunnel, when the different
customers shares the same physical interface?

Regards,

Lars Christensen
