The UG 13 minutes make note that the exchange MTU is 9000 bytes. Are other members configuring their routers for an MTU of 9000? I ask as TDS has not - we have stuck with the Ethernet standard 1500 bytes. If anyone on the exchange has set an MTU of 9000 and tries to send jumbo traffic to us, it will not be accepted and no indication will be sent back to the originator. (10d in the linked document below) If no one (or few) has setup their routers for an MTU of 9000, but we as a community wish to enable this, I would recommend that we schedule a flag day so that we can minimize blackholing of traffic across the exchange. While only a draft, see http://tools.ietf.org/html/draft-mlevy-ixp-jumboframes-00 for further information on IXP Jumbo Frame operation and conversion. For those that like presentations more than IETF drafts, Martin Levy (of Hurricane Electric at the time) presented this at RIPE 64 - https://ripe64.ripe.net/presentations/139-Hurricane_Electric_-_Martin_Levy_-...
