by having multiple areas, therefore ABR which deny routers and network LSA, you introduce summarization (ABR only send summary LSA, mean subnet info, not topology info) in your network. Thus you loose informations and do not have a complete topology of your network. I guess MPLS/TE prefer to seat on top of a real topology ?
Yes, summarization in the IGP has the potential to create blackholes and/or loops. This reminds me of: http://tools.ietf.org/id/draft-swallow-mpls-aggregate-fec-01.txt Mark.
