In a public exchange point where you're talking to multiple networks across a shared media it makes sense to do GigE, multiple GigE, 10GigE, etc,
What is the largest MTU that you can use across a GigE fabric?
I think this would be extremely foolhardy. The common number that all those using jumbo frames should support is 9000 bytes (not 9k aka 9216). This would probably need to be a condition of using GigE at the NAP, in order to achieve any kind of common support, and you're eliminating some vendor gige support (assuming their network can even carry the 9k packets TO the nap without requiring even more work and possible problems). Has anyone tested these maximium sized jumbo frames with 802.1q vlan tagging to see exactly how much (or how little) inter-vendor support really exists? -- Richard A Steenbergen <ras@e-gerbil.net> http://www.e-gerbil.net/humble PGP Key ID: 0x138EA177 (67 29 D7 BC E8 18 3E DA B2 46 B3 D8 14 36 FE B6)
