[c-nsp] MPLS Tutorial or Guide?

[Seth Mattinen]

Does anyone have a good intro or beginner's guide to MPLS that they
like? Something succinct and focused that's not a 500 page
my-first-Cisco book. The situation I'm thinking is putting someone in
front of some routers and switches in a lab setting and saying "take
these and set them up to do MPLS and create some xconnects for simulated
customers" with the assumption that they already have Cisco experience
and can build a non-MPLS network, but who is new to MPLS alone.
