I guess you're talking about the MX-series boxes:

The MX-series will do that just fine. Note, though, that the 
smallest 1Gbps DPC has 20 ports.

Alternatively, you can look at the M120. You can stick 2x 
10Gbps cFPC's in there + 2x 10Gbps PIC's in 2x FPC slots + 
1x 8-port 1Gbps PIC's in another FPC slot (the type 2 8-port 
PIC is 2:1 oversubscribed, while the type 3 version is line 
rate on all ports).

For the 8x Gig-E ports, you can mix and match with other 
less dense PIC's so as not to "put all your eggs in one 
basket", but be mindful of the limited number of FPC slots 
on this platform, especially since you'd need 4x 10Gbps 
ports on it. You may also consider the 1U EX-series switches 
and uplink the traffic via nx1Gps or a 10Gbps trunk, 
depending on your needs.

I wouldn't recommend anything larger without knowing your 
future growth needs.

Pretty standard with JunOS.

The suggested platforms have enough memory (control and data 
plane) to hold a full table.

Probably not appropriate for this list.

I'll send you some suggestions offline - but you might want 
to subscribe to 'c-nsp 'as well.

Cheers,

Mark.
