Deleting Dhcpv6 Client Bindings - Juniper JUNOSE 11.1.X - BROADBAND ACCESS CONFIGURATION GUIDE 6-4-2010 Configuration Manual

Deleting DHCPv6 Client Bindings

The JUNOSe Software enables you to manage your router's DHCPv6 local server
client bindings. The client binding associates an IPv6 prefix with a unique DHCP ID
(DUID) of the subscriber client. To view information about current DHCPv6 client
bindings and track lease times of a specific client binding, use the show ipv6
dhcpv6–local binding command.
To delete a client binding and the associated route configuration when the DHCPv6
client binding is no longer needed, use the dhcpv6 delete-binding command. You
can delete the DHCPv6 client bindings instead of waiting for the lease timer to expire.
Use the following keywords and variables with the dhcpv6 delete-binding command
to specify (filter) the client bindings you want to delete:
NOTE: After a stateful SRP switchover, in a scaled environment, the interface strings
associated with DHCPv6 client bindings might not be displayed in the output of the
show commands used to view information about client bindings if you issue the
show command immediately after a stateful SRP switchover. These show commands
display interface strings in the output only if the restoration of IPv6 interfaces on the
router is complete after the SRP warm switchover. After the restoration of IPv6
interfaces is complete, interface strings are displayed properly in the output of the
show commands available for this purpose.
You can remove all DHCPv6 client bindings, all DHCPv6 client bindings of a particular
type, or a specified DHCPv6 client binding that meets the deletion criteria you specify.

To delete all DHCPv6 client bindings on virtual router vr1:
host1:vr1#dhcpv6 delete-binding all
To delete DHCPv6 client bindings with the specified IPv6 prefix:

To delete a group of DHCPv6 client bindings that were assigned prefix from the
local pool:
