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.
