A year ago we built NREN backbone using TRILL instead of MPLS.
40 POPs, no central controller, RFC standardized TRILL protocol
i.e. L2 routing using IS-IS, no STP.
See my recent presentation at http://md.bts.sk/sanet-100g-2.pdf
for more details.
Much easier to setup, operate & maintain than MPLS and obviously much
lower cost. Based on 6-months production experience, my recommendation
would be to stay away from MPLS in the campus.
With kind regards,
