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:
1 Configure VLANs and IP unicast routing.
2 Enable the DHCP or BOOTP relay function, using the following command:
enable bootprelay
3 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}
