It's very strange issue, on openstack cluster we have
VxLAN between network and compute node and its using
1450 MTU (1500-50) because of encap header. Because of it some of my application not working properly. I am planning to increase MTU (jumbo)
9000 on all my openstack cluster node so question is in that case do i need to increase MTU on all my physical cisco switches? We don't want to do that.
Just wanted to know increase host MTU size required network switch MTU size to?
