Configuring BOOTP/DHCP Relay

You can use Network Voyager to enable BOOTP Relay on each interface. If the interface is enabled for relay, you can set up a number of servers to which to forward BOOTP requests. Enter a new IP address in the New Server text box for each server. To delete a server, turn it off.

Table 28 describes the parameters that you can configure for BOOTP relay

Table 28 BOOTP configuration parameters

Parameter	Description
Primary IP	If you enter an IP address in the Primary IP text box, all BOOTP requests received on
	the interface are stamped with this gateway address. This can be useful on interfaces
	with multiple IP addresses (aliases).
Wait Time	Specifies the minimum number of seconds to wait for a local configuration server to
	answer the boot request before forwarding the request through the interface. This delay
	provides an opportunity for a local configuration server to reply before attempting to
	relay to a remote server. Set the wait time to a sufficient length to allow the local
	configuration server to respond before the request is forwarded. If no local server is
	present, set the time to zero (0).
New Server	Enables forwarding of BOOTP requests to a configuration server. You can configure
	relay to multiple configuration servers independently on each interface. Configuring
	different servers on different interfaces provides load balancing, while configuring
	multiple servers on a single interface provides redundancy. The Server IP Address
	cannot be an address belonging to the local machine.
