Chapter 21: Configuring the DHCP External Server Application

Issue the ip dhcp-external auto-configure command with the

agent-circuit-identifier keyword from Global Configuration mode:

host1(config)#ip dhcp-external auto-configure agent-circuit-identifier

The use of the option 82 field enables you to stack an IP interface that is

associated with a particular subscriber over a dynamically created VLAN; the

VLAN is dynamically created based on the agent-circuit-id option (suboption 1)

that is contained in the DHCP option 82 field.

For information about configuring agent-circuit-id–based dynamic VLAN

subinterfaces, see the Configuring Dynamic Interfaces Using Bulk Configuration

chapter in JUNOSe Link Layer Configuration Guide.
