Re: customer identification

The MPLS core is ignorant of VPN customer data. All that the core sees is the top label, which identifies how to get to the PE router.

This is a good thing because it makes VPNs more scalable. If the core had to keep track of all customers, you would not be able to scale it too far.

Pls do remember to rate posts.
