A good practice on MX480s would be to keep upstream and downstream ports at

sure how much RLDRAM those NG cards have though.
It should be safe for at least 1.5M IPv4 FIB + reasonable IPv6 FIB.
It's pretty far future, unless you have large L3 MPLS VPN tables in
addition.
There are some other benefits running separate MPC for edge and core,
but it might not make financial sense. Obviously you want core
interfaces in separate MPCs, so having 3 MPC on smallest pop, and
potentially just 1 interface in each core MPC, may be just too high
premium for it.
I would not specifically plan on separate MPC for edge+core, unless
I'd knew that I'm going to have large VPN tables and 1.5M won't be
enough.
What the point to separate upstream and downstream port on different MPC
? (apart FIB size)
