Configure network settingsΒΆ
After you select a network topology in the deployment wizard, you can further configure Neutron L2 and L3 settings, as well as modify the node network group configuration.
Fuel creates the default node network group that includes the Public,
Storage, Management, Private, and Baremetal networks if you installed
the OpenStack Bare Metal service. The default node group also uses
the shared Admin network. You can modify parameters of the
Admin network for all other node network groups, if any, except the default
node network group.
Note
When you deploy an environment using Fuel, you can exclude specific IP addresses so that Fuel does not assign them. This helps to avoid network conflicts in case these IP addresses were previously reserved by other network entities.
To prevent IP address collisions, set the IP address range to be used by Fuel. For example, for nodes and VIPs, excluding the reserved IPs. In addition, you can specify multiple IP address ranges. If you have an IP address in use in the middle of the network IP address range, you can split the range to exclude the IP addresses in use.
Gateway will be set for all the networks when using multiple node network groups.
Additionally, Fuel provides a capability to configure networks using network templates. You can add or remove a network from a node network group through API when using network templates. A set of networks for a particular node network group on the Fuel web UI will be changed accordingly.
The Networks tab also contains the network verification section to perform the following checks:
- L2 connectivity checks between every node in the environment.
- DHCP discovery check on all nodes.
- Packages repository connectivity check from the Fuel Master node.
- Packages repository connectivity check from Fuel Slave nodes through Public and Admin (PXE) networks.
To configure network settings:
- In the Fuel web UI, click the Network tab.
- Select a setting and modify as needed.
Note
You can find IP addresses assigned to nodes in the Public and Management networks in the Management IP and Public IP fields in the summary section of a node details pop-up.
