Hi, Time to upgrade from 12.2(13)T16. All this router is doing is BGP and supporting some 802.1q subinterfaces. It's got a PA-GE card with a 100Base-SX GBIC inserted. I don't foresee any problems upgrading to 12.4, assuming there's enough room on the flash card, even though npe-300 is not officially supported. Do you? Thanks, Adam
