Abstract

Boot server support in an enterprise fabric network may be provided. A border device may forward, to a configuration server, a discovery message associated with a client device and the border device may forward, to a pre-boot server, the discovery message associated with a client device. The border device may then encapsulate, in response to receiving a reply to the discovery message from the configuration server and in response to receiving a reply to the discovery message from the pre-boot server, the reply to the discovery message from the pre-boot server using a Routing Locator (RLOC) from the reply to the discovery message from the configuration server. The encapsulated reply to the discovery message from the pre-boot server may include boot information. The border device may then forward the encapsulated reply to the discovery message from the pre-boot server to an edge device associated with the client device.
