In small edge PoP's, we attach an Arista 1U switch with tons of 1/10Gbps 
ports to an MX204 via 802.1Q. Works a treat. I've never been convinced 
by vendor-specific satellite systems :-).

On another note, the potential issue we might run into is pressure on 
control plane memory on the MX204 for us that run BGP Add-Paths. You can 
always upgrade the RE on an MX240/480/960, but the MX204 is fixed (and 
last time I checked, fiddling with Juniper RE memory was generally 
frowned upon).

Luckily, the MX10003 ships with 64GB of RAM, since it is now EoL.

The MX304 ships with 128GB of RAM, so anybody running Add-Paths on that 
box won't have an issue there.

Mark.
