detail command, it is necessary to match the displayed DUIDs and client systems. To do that, compare the value of distributed prefixes displayed in the binding information and the information of prefixes distributed to client system.

(e) Checking client setting

Check the client setting referring manuals provided with client.

(f)Procedure for restoring from duplicate distribution

If it is determined that duplicated prefixes were distributed to the same client by the IPv6DHCP server in this system, examine currently unused prefixes from the matching of displayed DUIDs and clients. Delete binding information for currently unused prefixes using the clear ipv6 dhcp binding <unused prefixes> command.

(2) Communication with the target of the prefix distribution is disabled

The following two possible causes of route information are not set when using the automatic route information setting feature for the route to prefix distribution target of the DHCP server in this system.

1.Information is configured but not distributed.

2.Operations or events have occurred that have an effect on functions relating to automatic route information setting.

It is possible to isolate the above reasons by comparing the results of the show ipv6 route -scommand which checks route information and distributed prefix information displayed by the show ipv6 dhcp server binding command.
