when installing undercloud with local_mtu > 1500 openstack udnercloud install failing, also if undercloud install with mtu 1500 we can not deploy overcloud with mtu larger then 1500 because we get same issue that neutron cannot create tenant network, global_physnet_mtu should be set to 0.
this seems to because of change:
https://review.opendev.org/#/c/612533/
Workaround:
echo " TenantNetPhysnetMtu: 0" | sudo tee -a /usr/share/openstack-tripleo-heat-templates/environments/undercloud.yaml
