General DHCP Relay Agent Configuration
To configure a DHCP relay agent, you must do the following:
1. Make sure that the gateway address used in relaying DHCP requests is
configured as an e1a address on the IP Network screen
(
Configuration
→
Interfaces
→
IP Network).
2. Assign domain names to the e1a addresses that will be used as DHCP
gateway addresses. Assign these domain names on the Domain Names
screen (
Configuration
→
DHCP Relay
→
Domain Names).
3. Configure the first eight NSP domain names on the Servers 1-8 screen
( Configuration
→
DHCP Relay Servers
→
Servers 1-8) and the last eight NSP
domain names on the Servers 9-16 screen ( Configuration
→
DHCP Relay
Servers
→
Servers 9-16).
On the appropriate DHCP Relay Servers screen, you will need to enter the
DHCP Server IP address for each domain. You will also need to determine
whether or not you want to use the authentication feature. There are several
fields that must be completed if you plan to use the authentication feature. In
addition, you must also give the administrator of the authentication server
some necessary information. See the following section,
Notes to the
Authentication Server Administrator , for more information.
For detailed information about the various DHCP relay screens, see the
HotWire
DSLAM for 8540 and 8546 DSL Cards User’s Guide. Also Appendix A, Network
Configuration Worksheets , in this guide provides worksheets to help you plan and
record your network configurations for dynamic IP addressing.
Notes to the Authentication Server Administrator
If the authentication process is to be invoked as part of dynamic addressing, the
authentication request from the DSLAM must be in either RADIUS or XTACACS
format. The authentication server will receive an authentication request from the
HotWire DSLAM before the end-user’s request for an address is relayed to the
DHCP server.
NOTE:
The IP source address for these requests will be the e1a interface IP address
associated with the domain.
The following sections describe the contents of the authentication request
message for a RADIUS authentication server and an XTACACS authentication
server.
