[j-nsp] Suggestion for Junos Version MX104

[Aaron]

Using 14.2R7.5, so far I've scaled my dual mx104 cgnat deployment to ~4,500 private ip customers with NAPT (nat overload) to a /25 of public address space per MX104 (so /24 total)

I think in 14.2R6 there was a MS-MIC-16G reboot issue that was occurring!  With 14.2R7.5 this no longer occurs :)

CPU seems like it's barely trying at ~55,000 nat translations per MX104.... our end-state goal is entire DSL community to be behind the dual MX104 cgnat boundary (~8,500 subs)

This cgnat is with MPLS L3VPN integration.  One vrf (ri) for inside nat domain, and another vrf (ri) for outside nat domain.  I can one-arm/nat-on-a-stick my MX104 PE's pretty much anywhere in my MPLS cloud and accomplish cgnat.

I also use AE's for the dual 10 gig, so 20 gig lag/lacp fat pipe, into the mpls network, and works fine.
