7.3. Creating Additional Floating IP Networks
Floating IP networks can use any bridge, not just
br-ex, as long as you meet the following conditions:
NeutronExternalNetworkBridgeis set to"''"in your network environment file.- You have mapped the additional bridge during deployment. For example, to map a new bridge called
br-floatingto thefloatingphysical network:$ openstack overcloud deploy --templates -e /usr/share/openstack-tripleo-heat-templates/environments/network-isolation.yaml -e ~/templates/network-environment.yaml --neutron-bridge-mappings datacenter:br-ex,floating:br-floating
Create the Floating IP network after creating the Overcloud using the following commands:
$ neutron net-create ext-net --router:external --provider:physical_network floating --provider:network_type vlan --provider:segmentation_id 105 $ neutron subnet-create --name ext-subnet --enable_dhcp=False --allocation-pool start=10.1.2.51,end=10.1.2.250 --gateway 10.1.2.1 ext-net 10.1.2.0/24
