Configuring Extended DHCP Local Server Dynamic Client Reconfiguration
The DHCP local server can initiate reconfiguration of its clients to avoid extended outages because of server configuration changes. In addition to requesting that the DHCP local server initiate reconfiguration, you can specify the reconfiguration behavior.
To configure dynamic reconfiguration of DHCP clients:
- Enable dynamic reconfiguration with default values for
all clients.
For DHCPv4:
[edit system services dhcp-local-server]user@host# set reconfigureFor DHCPv6:
[edit system services dhcp-local-server dhcpv6]user@host# set reconfigure - (Optional) Override the global configuration for a particular
group of clients.
For DHCPv4:
[edit system services dhcp-local-server group-name]user@host# set reconfigureFor DHCPv6:
[edit system services dhcp-local-server dhcpv6 group group-name]user@host# set reconfigure - (Optional) Configure how the server attempts reconfiguration.
See Configuring Dynamic Reconfiguration Attempts for DHCP Clients.
- (Optional) Configure the response to a failed reconfiguration.
See Configuring Deletion of the Client When Dynamic Reconfiguration Fails.
- (Optional) Configure the behavior in response to a RADIUS-initiated
disconnect.
See Configuring Reconfiguration of the Client on Receipt of RADIUS-Initiated Disconnect.
- (Optional) Configure a token for rudimentary server authentication.
See Configuring a Token for DHCP Local Server Authentication.
- (Optional) Initiate reconfiguration of some or all client
bindings.
See Requesting DHCP Local Server to Initiate Reconfiguration of Client Bindings.
- (Optional) Prevent DHCPv6 clients from binding if they
do not support reconfigure messages.
See Preventing Binding of Clients That Do Not Support Reconfigure Messages.
