request dhcpv6 server reconfigure
Syntax request dhcpv6 server reconfigure (all | address | client-id | interface interface-name |
logical-system logical-system-name | routing-instance routing-instance-name | session-id)
Release Information Command introduced in Junos OS Release 10.4.
Command introduced in Junos OS Release 12.3R2 for EX Series switches.
Description Initiate reconfiguration processing for the specified DHCPv6 clients if they are in the
bound state. If the clients are in the reconfiguring state, this command has no effect. If
the clients are in any state other than bound or reconfiguring, this command has the
same effect as the clear dhcpv6 server binding command.
When the local server state machine starts the reconfiguration process on a bound client,
the client transitions to the reconfigure state and the local server sends a reconfigure
message to the client. Because the client was in the bound state before entering the
reconfiguring state, all subscriber (or DHCP client) services, such as forwarding and
statistics, continue to work. An exponential back-off timer determines the interval at
which the reconfigure message is sent. If the final attempt is unsuccessful, the client is
returned to its original state by default. You can optionally include the clear-on-abort
statement to configure the client to be cleared when reconfiguration fails.
Options all—Initiate reconfiguration for all DHCPv6 clients.
address—Initiate reconfiguration for DHCPv6 client with the specified IPv6 address.
client-id—Initiate reconfiguration for DHCPv6 client with the specified client ID.
interface interface-name—Initiate reconfiguration for all DHCPv6 clients on this logical
interface (clients whose initial login requests were received over the specified
interface).
logical-system logical-system-name—Initiate reconfiguration for all DHCPv6 clients on
the specified logical system.
routing-instance routing-instance-name—Initiate reconfiguration reconfigured for all
DHCPv6 clients in the specified routing instance.
session-id—Initiate reconfiguration for DHCPv6 client with the specified session ID.
