Hi,

I am using Openstack Wallaby release on Ubuntu 20.04.

I am configuring openstack neutron for production. While setting mtu I am a bit confused between the 2 use cases.
 

Case 1 External (public) network mtu 1500 self service (tenent) network geneve mtu 9000 VLAN external network mtu 1500

Case 2 External (public) network mtu 9000 self service (tenent) network geneve mtu 9000 VLAN external network mtu 9000

I just want to know which case would be better for production.


I would really appreciate any input in this regard.

Thank you.

Regards,
Malik Obaid
