Jesse, I'm resurrecting this thread after a fairly lengthy discussion of MTU with Ben at the recent OpenStack summit. Have you given the topic any further thought toward implementation in a reasonable way? Can you elaborate on the architectural limitations? At the moment, the OpenStack implementat

Jesse, We can raise the MTU of the underlying network until it reaches the maximum value for the physical equipment, a common situation for 10+ Gbps data center networks. For example, if the physical equipment supports a maximum 9000 MTU, we can't further increase it to account for overlay protoco

Hi, Conventional OpenStack Networking service (neutron) drivers such as Open vSwitch and Linux bridge have a long history of MTU issues involving overlay networks. For example, consider the following typical virtual network architecture: 1) A provider network using native Ethernet or 802.1q taggi
