DHCPv6 insert options into lease file

[Jan.Lampikari at haminanenergia.fi]

Hi all,

We are looking for a solution to record option 18 (Interface-ID) and option 37 (Remote-ID) into the lease file dhcpd6.leases. We would like to see where the prefixes are assigned exactly (To which DSLAM port for example). The desired outcome would be to have similar functionality as option 82 provides in IPv4.

The current setup is as follows:
DHCPv6 server <-> DHCPv6 relay <-> DHCPv6 client <-> Host machine

With Wireshark we can see the relay inserts both options in the relay-forw message but when the prefix has been assigned they are not saved along with the prefix information into the lease file.

The current lease entry contains the following lines:

ia-pd " ....... " {
cltt 4 2014/01/23 09:19:20;
iaprefix 2a00:xxxx:xxxx:xxxx::/64 {
preferred-life 375;
max-life 600;
ends 4 2014/01/23 09:29:20;
}
}

DHCPv6 server is configured as below:

default-lease-time 600;
max-lease-time 7200;
log-facility local7;

subnet6 2a00:xxxx:xxxx:/48 {
prefix6 2a00:xxxx:xxxx:xxxx:: 2a00:xxxx:xxxx:xxxx:: /64;
}

Currently with IPv4 the same has been done as follows and we would like to achieve something similar with IPv6 disregarding the lease limit.

if exists agent.circuit-id {
log (info, concat("Lease for ", binary-to-ascii (10, 8, ".", leased-address), " is connected to CPE ", option agent.remote-id, " at BST ", option agent.circuit-id));
}

class "CPE" {
        spawn with option agent.remote-id;
        lease limit 5;
}

subnet xxx.xxx.xxx.xxx netmask xxx.xxx.xxx.xxx {
        option routers xxx.xxx.xxx.xxx;
        option domain-name-servers xxx.xxx.xxx.xxx, xxx.xxx.xxx.xxx;
        option broadcast-address xxx.xxx.xxx.xxx;
        default-lease-time 86400;

pool{

        allow members of "CPE";
                             range xxx.xxx.xxx.xxx xxx.xxx.xxx.xxx;

}
}

Any advice is greatly appreciated.
