Hi Team, I am trying to deploy an Openstack Train using TripleO having 3 Controllers and 1 Compute. Without Network Isolation, I have deployed it successfully. Now, I am trying to segregate my network traffic using multiple-nics-vlan configuration generated via the below command /tools/process-templates.py -o ~/openstack-tripleo-heat-templates-rendered -n /home/stack/network_data.yaml -r /home/stack/templates/roles_data.yaml The command used for deploying the overcloud is openstack overcloud deploy --templates \ *-n /home/stack/templates/network_data.yaml \* -r /home/stack/templates/roles_data.yaml \ -e /home/stack/templates/node-info.yaml \ *...* *-e /home/stack/templates/environments/network-isolation.yaml \-e /home/stack/templates/environments/network-environment.yaml \* *...* It is failing just after the ovs bridge gets created and external nic vlan is attached to the bridge. [image: MicrosoftTeams-image (1).png] MAC Address of br-ex is same as the MAC of the interface specified in file network/config/multiple-nics-vlan/controller.yaml For testing, If I assign an IP address to that interface, it is reachable to GW. But, in case IP is assigned to VLAN 418 and it is added in the br-ex, Gateway remains unreachable. Please suggest
