Sorry. I was presuming we were talking about about UDP fragmentation with IPv4, as this was the bug report and of course GCE doesn't support IPv6.
IPv6 jumbograms are a whole different kettle of fish, as they are really handled at the IP layer, and are supposed to only be for cases where you have an MTU > 65,575 bytes. As that link describes, the UDP protocol itself doesn't do any fragmentation or reassembly of those packets. RFC 2147 is really just an update to handle the fact that IPv6 can have a single packet that is larger than an IPv4 packet.
- jacquesm 11y agoIt is me that should say 'sorry', I found this on a bit of documentation about GCE: "Note: Compute Engine networks only support point-to-point IPv4 traffic. Broadcast and Multicast are not supported." https://cloud.google.com/compute/docs/networking?hl=en https://cloud.google.com/compute/docs/networking?hl=en And this: https://code.google.com/p/google-compute-engine/issues/detail?id=8 https://code.google.com/p/google-compute-engine/issues/detai... So: Sorry!
