You get your highend GigE switch, you set it to 4470 MTU. You use either 7200 with PA-GE, or GSR with 1GE (avoid 3GE here, 2450 MTU doesn't cut it).
Maybe 4470, but some operators prefer ~9K. Different operators might have different circumstances and hence different opinions. If I were running an exchange point, I'd configure the exchange switch for ~9K and leave the choice of MTU on the connecting device up to my customers -- because that would maximise the potential customer base and I am a capitalist. Btw, some old GSR 1 GigE interfaces did not support anything above IEEE-standard MTU. I infer from your note that there are now some GSR interface cards that do support larger than IEEE-standard MTU. I haven't used any of the supposed new cards, but deployed several of the older ones that didn't support anything above IEEE-standard MTU on GigE. Or maybe it was an IOS thing that changed in the meantime. Cheers, Ran rja () inet org
