The E Series router provides a DHCP access model, which enables you to integrate the
router into an existing RADIUS-based operation support system (OSS). In the DHCP
access model, a DHCP local server or DHCP external service is configured, but the E Series
router does not have direct interaction with an OSS or a policy server, such as the SRC
software. The router passes the client's DHCP options, client's media access control
(MAC) address and, if appropriate, the DHCP relay's IP address in RADIUS requests for
authentication.
To configure the DHCP access model to pass the client's information in RADIUS requests,
you enable the DHCP options feature, then specify the client information to be passed
to RADIUS. You can specify that the client's MAC address be included in the request. You
can also specify that the DHCP relay's IP address be sent, if appropriate. For descriptions
of the RADIUS attributes used with the DHCP access model, see "Configuring RADIUS
Attributes" on page 167.
DHCP proxy client support enables the router to obtain an IP address from a DHCP server
for a remote PPP client. Each virtual router (acting as a DHCP proxy client) can query up
to five DHCP servers.
