The PXE Boot Network

You can set up a Boot network for booting all nodes to allow a non-standard management network configuration.

The internal management network is used for booting of new hosts and the Boot network is not required. However, there are scenarios where the internal management network cannot be used for booting of new hosts. For example, if the internal management network needs to be on a -tagged network for deployment reasons, or if it must support IPv6, you must configure the optional untagged boot network for booting of new hosts using IPv4.

Note

does not support IPv6 Booting.

See The PXE Boot Network <network-planning-the-pxe-boot-network> for details.
