Hi Team, We have deployed tripl0 Train using two tenant networks by configuring the parameters for additional networks. environments.yaml: *NeutronBridgeMappings: datacentre:br-tenant,datacentre2:br-extratenant* in environments/network-environment.yaml * NeutronNetworkVLANRanges: 'datacentre:1:500,datacentre2:501:1000'* and have also isolated and separated the physical nic configuration for ovs in network/config/bond-with-vlans/compute.yaml with this setting, overcloud is deployed and the network is getting created, Checking further, in Controller configs(/etc/neutron/plugins/ml2/) we see the changes as below, which looks fine: *[ml2_type_vlan]* *network_vlan_ranges=datacentre:1:500,datacentre2:501:1000* *but it is also allowing* the network to be created from the wrong network segment range. For example, while creating a network: - openstack network create --share --provider-network-type vlan --provider-physical-network datacentre2 --provider-segment 420 datacenter_2_420 -provider-physical-network- *"datacentre2"* is having VLAN range from 501-1000 and if I am passing the provider segment as 420(which is out of range) then *also a network is getting created.* This does not look fine. please help share any inputs on the same. -- ~ Lokendra skype: lokendrarathour
