Yes... the MX304 is awesome, but the price is going to be crazy. Possibly ~10x MX204 if fully loaded.

What does the ACX7100 have in terms of FIB/RIB ? Juniper is making it very hard as of late to find that information. I'd be curious if the ACX could do brder router duties with multiple full BGP feeds (which the MX204 has no problem with at all)
