MPLS and VLAN info

I need to educate some coworkers (who aren't all that familiar with
networks) and my boss on the security advantages of MPLS and VLAN's. I
guess I don't seem to be communiating it very well because they just don't
get it. Can anyone point me to some good technical docs that specifically
deal with some of the benefints of MPLS and VLAN's. Specifically security
related would help.

Unless you are encrypting traffic, the only security advantage of MPLS and
VLANS is circuit isolation like FR or ATM.

Personally, I like my traffic encrypted.
