Where you've read it? ASR is a WAN services box. Positioned
for SPs only as a multi-service edge/SBC/route reflector (with RP2).

This discussion is almost weekly here on cisco-nsp@, but
focuses mainly on the PFC3B/3C vs PFC3BXL/CXL for 6500/7600.

It's an edge not peering box, if you need 1mln IPv4 prefixes in FIB
go for either ASR1002 with ESP10 or 7600S with RSP720 CXL version,
depending on the actual bandwidth you need to push through the box.
