I’m using a pair of MX104’s for 10 gig and a MS-MIC-16G for CGNat integrated with L3VPN’s (LDP for label distro), just fine.  About 5,000 DSL broadband customer behind them, on a /24 public ip nat pool.  Some nice IP savings there.

Can’t speak to your BFP, RSVP-TE requirement as I never needed that on mine.
