Hi there,
currently I want to get a DHCPv6 prefix delegation with a fixed assignment working with a mobile operator.
The CISCO P-GW is sending me the 3GPP-IMSI as a USER-CLASS:

Interface-Id

Consequently I was configuring the DHCP - Server as follows:
....
host myrouter {
host-identifier option user-class "00:01:02:03:04:05:06:07:08:09";
fixed-prefix6 2001:2001:20:200::/56;
}
...
Unfortunately I got stuck :(!
Could anyone give me an advice?
Thank you in advance
Wolfgang
