| Network name | Subnet size | Needs to be externally routable**? | Function | |
|---|---|---|---|---|
| 'oob' | Any* | No | Provides the connectivity between the Build server and RC and then RC and Rover/Unicycle nodes for Redfish API calls to configure/interogate the servers' BIOS. | |
| 'host' | Any* | Yes | Provides the edge site's isolated network for MaaS provisioning (MaaS runs on the genesis node once provisioned). It does not need to be routable to any other network. | |
| 'pxe' | /24 fixed in R1 | No | Provides a remote site's L2 local network for MaaS provisioning. | |
| 'ksn' | /24 fixed in R1 | No | Provides the connectivity and BGP route exchange for the calico network. | |
| ' | ksnstorage' | /24 fixed in R1 | No | Provides the openstack storage network |
| 'neutron' | /24 fixed in R1 | No | Provides the openstack neutron network | |
| 'datapath' | Defined in openstack | No *** | Provides the openstack datapath network for the SR-IOV variant VMs | |
| 'vxlan' | /24 fixed in R1 | No**** | Provides the openstack storage network for the OVS-DPDK variant VMs |
Notes:
* The 'oob' network may be split in to multiple subnets if required. Each server except the Build Server (and the RC if built on a VM) requires an iDRAC/iLO address which must be manually pre-provisioned into the server.
