Juniper EX3400 Features Guide

NOTE: To use the DHCP local server option 82 matching feature with an IPv4
address-assignment pool, you must ensure that the option-82 statement is
included in the dhcp-attributes statement for the address-assignment pool.
To configure the matching order the extended DHCP local server uses to determine the
address-assignment pool used for a client:
1. Access the pool-match-order configuration.
[edit system services dhcp-local-server]
user@host# edit pool-match-order
2. Specify the pool matching methods in the order in which the router (switch) performs
the methods. You can specify the methods in any order. All methods are optional—the
router (switch) uses the ip-address-first method by default.
•
Configure the router (switch) to use an external addressing authority.
[edit system services dhcp-local-server pool-match-order]
user@host# set external-authority
•
Configure the router (switch) to use the ip-address-first method.
[edit system services dhcp-local-server pool-match-order]
user@host# set ip-address-first
•
(IPv4 address-assignment pools only) Specify the option 82 matching method.
[edit system services dhcp-local-server pool-match-order]
user@host# set option-82

Example: Extended DHCP Local Server Configuration with Optional Pool Matching
This example shows an extended DHCP local server configuration that includes optional
IPv4 address-assignment pool matching and interface groups. For pool matching, this
configuration specifies that the DHCP local server first check the response from an
external authentication authority (for example, RADIUS) and use the Framed-IPv6-Pool
attribute to determine the address-assignment pool to use for the client address. If no
external authority match is found, the DHCP local server then uses ip-address-first
matching together with the option 82 information to match the named address range
