James Harper wrote: 802.1q lives under IP. That's right. But the VLAN exposes a virtual interface. That virtual interface should automatically have an MTU size of the underlying interface minus 4 bytes (for the VLAN tag). And then IP fragmentation, working on top of that virtual Ethernet interface, should perform fragmentation correctly. Sorry if I was unclear. _______________________________________________ Xen-users mailing list Xen-users@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-users |
