Once IP unicast routing is configured, you can configure the Summit to forward 
Dynamic Host Configuration Protocol (DHCP) or BOOTP requests coming from clients 
on subnets being service by the Summit and going to hosts on different subnets. This 
feature can be used in various applications, including DHCP services between Windows 
NT servers and clients running Windows 95. To configure the relay function, do the 
following:

Configure VLANs and IP unicast routing.

Enable the DHCP or BOOTP relay function, using the following command:

enable bootprelay

Configure the addresses to which DHCP or BOOTP requests should be directed, 
using the following command:

config bootprelay add <ipaddress>

To delete an entry, use the following command:

config bootprelay delete {<ipaddress> | all}
