Hi All,

is ISC DHCP supports the below feature(below is the wide client support) ->
    i.e. assignment of prefixes to the interfaces specifed.

The followings are a sample configuration to be delegated an IPv6 prefix
     from an upstream service provider.  With this configuration dhcp6c will
     send solicit messages containing an IA_PD option, with an IAID 0, on to
     an upstream PPP link, ppp0.  After receiving some prefixes from a server,
     dhcp6c will then configure derived IPv6 prefixes with the SLA ID 1 on a
     local ethernet interface, ne0.  Note that the IAID for the id-assoc
     statement is 0 according to the default.

     interface ppp0 {
             send ia-pd 0;
     };

     id-assoc pd {
             prefix-interface ne0 {
                     sla-id 1;
             };
     };

     If a shared secret should be configured in both the client and the server
     for DHCPv6 authentication, it would be specified in the configuration
     file as follows:

     keyinfo kame-key {
             realm "kame.net";
             keyid 1;
             secret "5pvW2g48OHPvkYMJSw0vZA==";
     };

Thanks in Advance,

Best Regards,
Venkatesh.
