Re: Mpls vs mpls lite

Another VRF-lite application is centralized shared services - i.e. you
may have a common VRF for servers and clients on their own VRF. The
trick is that the server VRF may see all the client routes, but the
clients do not see each other.

Anyway, VRF-lite or VRF-lite end-to-end is just a marketing term for
using just VRF (and GRE) as a path isolation alternative instead of
MPLS VPN, i.e. the full VRF, MPLS, and MP-BGP suite.

HTH,
