VXLAN/Tenant Networks are created with MTU=1450 after an upgrade to Red Hat OpenStack Platform 9
Issue
After an upgrade to OSP 9, new tenant networks are being created with MTU=1450
(1500 - VXLAN overhead of 50bytes). Can this be set back to 1500 so that guests/instances have an MTU of 1500?
- Same behavior is noticed under OSP 10 deployed templates.
Environment
- Red Hat OpenStack Platform 9.0.
