Hi, I'm running openstack (IceHouse) configured for provider networks.
For a tenant i've created the network/ subnet using the below commands and everything works as expected. neutron net-create --tenant-id f557a3f5303d4e7c9218c5539456eb37 --provider:physical_network=physnet2 --provider:network_type=vlan --provider:segmentation_id=315 ih-lwr-ci-provider-vlan315 neutron subnet-create Openstack-External-vlan55 10.82.42.0/24 --name Openstack-External-vlan55-subnet --no-gateway --host-route destination= 0.0.0.0/0,nexthop=10.82.42.1 --allocation-pool start=10.82.42.223,end=10.82.42.254 Now my questions/ use cases are: 1. For a 2nd tenant, can i map it to the same subnet created for tenant 1? If the answer is to create same net/ subnet (same segmentation_id - i.e vlans) for tenant 2, how will dhcp agent avoid IP duplication. 2. Is having multiple tenants pointing to same provider network (net/ subnet/ vlan) is not possible what options do i have? Only to create a new net/ subnet based on new vlan and allocated to tenant 2? Cheers, Dani
