>From my experience with an ASR9000, I'd agree with Roland. The ASR9000 has many more features and abilities that make it more attractive on the edge rather than in the core. Depending on how your MPLS core design is all you need to do is route between the PE's and not carry all the different routes meaning your core doesn't need as powerful a router as all you need to do is carry your internal igp protocol routes and push raw ip traffic. Another factor is how many routers are involved in your design, how many routes you are carrying, and what services you are offering or plan to offer to your customers.
