Configuring DHCP relay to allow CPE clients to obtain an address
RFC 951, Bootstrap Protocol (BOOTP), describes an IP/UDP bootstrap protocol that
allows a diskless CPE client to discover its own IP address, the address of a server
host, and the name of a configuration file to be loaded into memory and executed.
RFC 2131, The Dynamic Host Configuration Protocol (DHCP) describes a framework for
automatic configuration of IP hosts, and RFC 2132, DHCP Options and BOOTP Vendor
Information Extensions describes BOOTP additions that can be used as DHCP options.
When the requesting client machine does not reside on the same IP network as a
BOOTP or DHCP server, as is typically the case for DSL subscriber connections, the
IP2000 must be configured to operate as a DHCP relay agent. A relay agent is an
intervening system that transfers messages between the client (the requesting host
system) and the server.
RFC 3046, DHCP Relay Agent Information Option describes information inserted by the
DHCP relay agent when forwarding client-originated DHCP packets to a DHCP server.
Servers recognizing the Relay Agent Information option may use the information to
implement IP address or other parameter assignment policies. The DHCP Server
echoes the option back verbatim to the relay agent in server-to-client replies, and the
relay agent strips the option before forwarding the reply to the client.
Overview of DHCP relay configuration settings
For information about DHCP option 82, see “Configuring DHCP Option 82 for use
with DHCP relay” on page 4-27. The following parameters (shown with default
settings) configure DHCP relay:
[in IP-GLOBAL:bootp-relay]
active = no
bootp-servers = [ 0.0.0.0 0.0.0.0 ]
