If I remember correctly from M5/M10, they uses FEB (built-into-Chassis FPC version), and each FEB (row) has restriction up to 3.6Gbps rate. So total aggregated bandwidth can not go over this limit. If you install 4GE (4 of 1-port GigE PIC) in same FEB row, you can use 0.9Gbps in average per PIC with max 1Gbps. :-) Also, 4GE PIC (single PIC with 4-port GigE) has limitation for up to 1Gbps aggregated bandwidth, too. M7i/M10i has redundant RE options from M5/M10. So no differencce except M7i with built-in GigE into chassis. If you really wants to use GigE per trunk, you may have to use PE-1GE-SFP instead of single quad-port GigE PIC. For memory, it may be sufficient with 768MB memory for now, But if I were you, I would go with 1.5GB with new RE. It's pain in the XXX to add more memory later from production system. If you are concerned about the budget, you can use after-market memory. Hyun Donald Stahl wrote:
