One key thing to keep in mind is that vxrs with your desired npe have 2 hw buses, the even slots are 1 bus, the odds are the other, so be sure to distribute bw accordingly. http://www.cisco.com/en/US/products/hw/modules/ps2033/products_configuration _guide_chapter09186a00801056f4.html is a good link for looking this stuff over. I have a minor comment on the subint thing, in the past I worked for a provider that had a non vxr 7206 with ONE t3 and all thos esubints/maps and it worked well.
