Configuring Dynamic Client Reconfiguration of Extended Local Server Clients
The DHCP local server can initiate reconfiguration of its clients to avoid extended outages
because of server configuration changes. You can enable dynamic reconfiguration for
all DHCP clients or only the DHCP clients serviced by a specified group of interfaces, and
you can modify the behavior accordingly.
Starting in Junos OS Release 14.1, you can modify the behavior of the process in which
the DHCP local server initiates reconfiguration of its clients by including the appropriate
configuration statements. You can provide the statements at the [edit system services
dhcp-local-server reconfigure] hierarchy level for all DHCPv4 clients, and at the [edit
system services dhcp-local-server dhcpv6 reconfigure] hierarchy level for all DHCPv6
clients. To override this global configuration for only the DHCP clients serviced by a
specified group of interfaces, you can include the statements with different values at the
[edit system services dhcp-local-server group group-name reconfigure] hierarchy level for
DHCPv4 clients, and at the [edit system services dhcp-local-server dhcpv6 group
group-name reconfigure] hierarchy level for DHCPv6 clients.
To configure dynamic reconfiguration of DHCP clients:
1. Enable dynamic reconfiguration with default values for all clients.
For DHCPv4:
[edit system services dhcp-local-server]
user@host# set reconfigure
For DHCPv6:
[edit system services dhcp-local-server dhcpv6]
user@host# set reconfigure
2. (Optional) Enable dynamic reconfiguration for only the DHCP clients serviced by a
group of interfaces.
For DHCPv4:
[edit system services dhcp-local-server group-name]
user@host# set reconfigure
