I don't think it's relevant for Neutron at all. It sounds more like OVS issue (?). Note that this email thread may be of relevance here: http://openvswitch.org/pipermail/dev/2016-June/073190.html It talks about a different aspect of MTU vs. OVS bridge, but the root cause, I think, is related: ovs bridges do not generally allow to maintain different MTUs on the same switch. It's not clear if it's to be supported by OVS community. OVS 2.6 will introduce the mtu_request column to Interface table, which allows this setting to apply even after adding the Ethernet interface. Cascardo. This will only be available after OVS 2.6 is released. Anything you can do to workaround it on Neutron? Cascardo. Development Management has reviewed and declined this request. You may appeal this decision by reopening this request. |
