BOOP/DHCP servers on different subnets. BOOTP and DHCP relay are disabled by
default.
Enabling BOOTP or DHCP Relay
To enable BOOTP or DHCP relay:
1 Configure VLANs and IP unicast routing before enabling BOOTP and DHCP
relay. VLANs are discussed at length in Chapter 5, Setting Up SafeGuard Switches.
Steps for configuring unicast routing are found in Configuring Static Routing on
page 191.
2 Enable the DHCP and BOOTP relay function, using the bootpdhcprelay enable
command. The no version of the command disables the forwarding of relay
requests. These Global Configuration commands have the following syntax:
bootpdhcprelay enable
no bootpdhcprelay enable
The commands have no parameters or variables.
3 Specify the server address for DHCP or BOOTP relay requests, using the
bootpdhcprelay serverip Global Configuration command. The no version of the
command reinstates the default server IP address (0.0.0.0).
bootpdhcprelay serverip ipaddr
no bootpdhcprelay serverip
