So assuming I got with something like this setup: http://www.ebay.com/itm/Juniper-MX960BASE-AC-10x-DPC-R-4XGE-XFP-MS-DPC-1yrWrnty-Free-Ship-40x-10G-MX960-/351615023814?hash=item51dde37ac6:g:WUcAAOSwLVZViHc~
That has RE-2000's, Regular SCBs, and all DPC linecards. Would these all be able to run at line rate? On Thu, Jan 14, 2016 at 4:19 PM, Christopher E.
