DHCP and BOOTP relay
You can configure the router to relay Dynamic Host Configuration Protocol (DHCP) and
BOOTstrap Protocol (BOOTP) client broadcasts to a server on a different segment of the
network. When you configure DHCP and BOOTP relay, you can control how the router relays
DHCP and BOOTP packets. The router also relays replies from the server back to the client.
The Branch Gateway can alternatively function as a DHCP server, providing DHCP service to
local devices. For information about configuring DHCP server on the Branch Gateway, see
DHCP server on page 447. For information about configuring DHCP client on the Branch
Gateway, see DHCP client configuration on page 204.
