Good MPLS/VPLS book?

[mhelmest at uvic.ca (Michael Helmeste)]

   Does anyone have a favorite book or resource discussing MPLS and all 
associated Lego blocks (e.g. LDP, TE, VPLS, martini, mBGP et. al.)?

   I understand the basics of what MPLS is and how you create a circuit from
A to B but I'm afraid it still escapes me when trying to figure out how 
someone would, say, create a multicast capable VPN with 5 edge points.

   Any pointers to a good way to reduce my level of ignorance on this 
subject would be appreciated. Vendor literature doesn't bother me as long 
as the concepts are there.

   Regards,
