What you're referring to are the ACX500 through to the ACX4000 units. The ACX5000 (5048 and 5096, respectively) are Metro-E switches (IP/MPLS routers, really). Unlike the other ACX models, they do not come with any non-Ethernet ports. Mark.

They are primarily designed as layer 1(TDM)/2 backhaul devices and i'm not sure they can do a full table. They do have full JunOS MPLS features. Could be a way to use MPLS-TE to move the layer 2 back to a core location and terminate later 3 there. Would give you some flexibility over just doing ethernet stuff as I mentioned in the first paragraph. The ACX5000 series are Ethernet-only switches. They hold about 120,000 entries in FIB, and as of today despite all the RAM, are only sold with support for 300,000 entries in RIB. The chipset is not Juniper in-house, though; so make sure all your features work. Mark.

You can leverage netconf yang model as its cisco edge or other flavor choice You can unicast if you want more data as we've done EFI and evaluated them in our labs But it only holds 20,000 IPv4 entries in FIB - quite paltry if he wants a full table. Then again, BGP-SD + selective routing into FIB could fix that. Mark.
