Chapter 9: Forcing Dynamic Reconfiguration of Clients from a DHCP Local Server
For DHCPv6:
[edit system services dhcp-local-server dhcpv6 group group-name]
user@host# set reconfigure
(Optional) Configure an authentication token. The DHCP local server then includes

this token inside the authentication option when it sends forcerenew or reconfigure
messages. If the service provider has previously configured the DHCP client with this
token, then the client can compare that token against the newly received token, and
reject the message if the tokens do not match. This functionality corresponds to RFC
3118, Authentication for DHCP Messages, section 4.
For all clients:

For DHCPv4:
[edit system services dhcp-local-server reconfigure]

For DHCPv6:
[edit system services dhcp-local-server dhcpv6 reconfigure]
user@host# set token
For only the DHCP clients serviced by a group of interfaces:

reconfiguration. Including this statement causes the server to discard solicit messages
from nonsupporting clients; consequently the server does not bind these clients.
