Remote OS Installation

Troubleshooting: Working with Routers

Because Remote OS Installation client service requests are based on the DHCP discovery process, configuring your network to support Remote OS Installation across routers has the same requirements as supporting DHCP across routers. If your environment contains routers between clients and your RIS servers, ensure that DHCP broadcasts from clients (that are used to initiate a remote boot session with RIS servers) are used properly by the routers.

Routers that are configured to forward DHCP broadcasts also forward Remote OS Installation client service requests, however you must ensure that these requests are forwarded to the proper RIS servers in addition to any DHCP servers. Depending on the router models in use, the specific router configuration of DHCP broadcast forwarding might be supported to either a subnet (or router interface), or to a specific host. If your DHCP servers and RIS servers are separate computers, ensure that the routers forwarding DHCP broadcasts are designed so that both the DHCP and RIS servers receive the client broadcasts, otherwise the client does not receive a reply to its remote boot request.
