The router offers an embedded DHCP server, known as the DHCP local server. The DHCP
local server has two modes: equal-access and standalone.
NOTE: E Series routers also support an embedded DHCP version 6 (DHCPv6)
local server. The DHCPv6 local server provides a subset of the features of
the DHCP local server. For information about configuring the DHCPv6 local
server, see "Configuring the DHCPv6 Local Server" on page 485.
In equal-access mode, the DHCP local server works with the Juniper Networks SRC
software to provide an advanced subscriber configuration and management service.
In standalone mode, the DHCP local server provides a basic DHCP service, and also
allows you to configure AAA authentication for incoming DHCP clients. Also, after
successful authentication, the DHCP local server uses the information in the client's
AAA subscriber record together with the client's DHCP parameters to select the IP
address pool used for address assignment.
DHCP local server also supports RADIUS accounting, including interim accounting, in
standalone mode. This feature allows you to use RADIUS start and stop attributes to
track user events such as the lifetime of an IP address.
You can use DHCP to configure the router to allow remote access to non-PPP clients.
DHCP-based access is also an alternative to PPP in environments such as Public Wireless
