Bootp Relay

Bootp (bootstrap protocol) is an optional feature used by a network client to obtain configuration information from a network server (the Bootp server), such as its IP address and the name of the boot file to be loaded into memory. The use of a Bootp server reduces the amount of configuration that needs to be done throughout the network, while insuring that the same IP address is not used simultaneously by two different clients.

In the simplest scenario, the client resides on the same IP network as the Bootp server; however, Bootp also allows for clients to be booted remotely from servers that are not on the same network or subnet. In those cases, the help of a Bootp relay agent is needed.

The Bootp relay agent takes the Bootp request from the client and relays it to the server on the other network. If the server is more than one hop away, the relay agent relays the request to the next higher-level relay agent, until the request finally reaches the Bootp server. The server prepares the boot reply, then sends it back to the client via the relay agent.

If multiple IP addresses are configured on the LAN (multi-homing), the bootp client will only be able to get an IP address for the first IP segment that is configured on the Passport 4400 LAN. For example, If the Passport 4400 unit contains IP addresses of 10.0.0.1, 11.0.0.1, 12.0.0.1, and 192.168.18.1, the bootp client will only be able to get an IP address on the 10.0.0.1 network.

Use the following Configurator or CLI procedure to configure the Passport 4400 for Bootp relay:
