[c-nsp] vrf-lite vs. MPLS vrf

[Randy Densen]

This is my first post.
I have 2 questions:

1) does The cisco-nsp Archives have a search function to look for posts that
may have already been addressed and/or answered?

2)  What criteria would you use to determine whether a Metro Ethernet
network should move forward with VRF-Lite or use MPLS vrf's?  Personally, I
would like to have a layer 2 network (ethernet relay service, similar to
what a large telco would do, then overlay a Layer 3 Internet and VPN service
for granularity and flexibility).
Pros? Cons? Preference?

thanks
