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. -Aaron
