Linux bridge does not "create" a tap interface. Someone created that Linux bridge, then created a tap interface and then added that tap interface as a port to the Linux bridge. I am guessing that this is a openstack deployment with Linux bridge connected to OVS using a connector (veth pair?).
So if you want MTU setting along the way, you will have to start looking at how and who creates those interfaces. If you are trying to do this to solve some tunnelling issue, then it is probably simpler to reduce the MTU in the VM. > > Thanks, > Bhavin Shah > > .:|:.:|:.
