For NSX-T Data Center deployments, you create an external network to contain the floating IP addresses of future tenant logical (tier-1) routers.
Procedure
- Log in to the VMware Integrated OpenStack dashboard as a cloud administrator.
- Select the admin project from the drop-down menu in the title bar.
- Select .
- Click Create Network and configure the provider network.
Option Description Name Enter a name for the network.
Project Select the desired project from the drop-down menu.
Provider Network Type Select Local to connect tenant logical routers to the default tier-0 router or External to connect tenant logical routers to another tier-0 router.
Physical Network If you selected External as the provider network type, enter the UUID of the tier-0 router to which you want to connect future tenant logical routers.
- Select Enable Admin State, External Network, and Create Subnet.
- If you want multiple projects to use the external network, select Shared.
- Click Next and configure the subnet.
Option Description Subnet Name Enter a name for the subnet.
Network Address Enter the IP address range for the subnet in CIDR format (for example, 192.0.2.0/24).
IP Version Select IPv4 or IPv6.
Gateway IP Enter the gateway IP address. If you do not enter a value, the first IP address in the subnet is used. If you do not want a gateway on the subnet, select Disable Gateway.
- Click Next and deselect Enable DHCP.
- (Optional) Configure additional settings for the subnet.
- Under Allocation Pools, enter IP address pools from which to allocate the floating IP addresses of tenant logical routers. Enter pools as two IP addresses separated by a comma (for example, 192.0.2.10,192.0.2.15). If you do not specify any IP address pools, the entire subnet is available for allocation.
- Under DNS Name Servers, enter the IP address of one or more DNS servers to use on the subnet.
- Under Host Routes, enter additional routes to advertise to the hosts on the subnet. Enter routes as the destination IP address in CIDR format and the next hop separated by a comma (for example, 192.0.2.0/24,192.51.100.1).
- Click Create.
