After fantastic help from these boards before I got IPv6 working from a pool on the LNS. However, that was in a lab test environment.
We now have the equipment in the data centres and we need IPv6 addresses (Prefix's) to be assigned via the RADIUS. So, using the "framed-ipv6-prefix" VSA I assign an address for the subscriber. This is the result from the LNS perspective:
Run show subscribers
si-1/0/0.3221262969 188.8.131.52 email@example.com default:default* 2455:6880:2600:4446::/64
The run show subscribers extensive shows the following:
Type: L2TPUser Name: firstname.lastname@example.orgIP Address: 184.108.40.206IP Netmask: 255.255.255.255Primary DNS Address: 220.127.116.11Secondary DNS Address: 18.104.22.168IPv6 User Prefix: 2455:6880:2600:4446::/64Logical System: defaultRouting Instance: defaultInterface: si-1/0/0.3221262969Interface type: DynamicUnderlying Interface: si-1/0/0.3221262969Dynamic Profile Name: dyn-lns-profileDynamic Profile Version: 8State: ActiveRadius Accounting ID: 37499Session ID: 37499PFE Flow ID: 37547Login Time: 2018-06-12 08:31:23 UTCIPv6 Framed Interface Id: 80a7:97b0:d2ed:f535Accounting interval: 600
Which seems to show that the subscriber has an IPv6 address, and it is the one that the RADIUS supplied. However, when I attach to the DSL CPE and complete an "ipconfig" there is no IPv6 address and the WAN interface on the CPE also has no IPv6 address.
Is there anything I need to configure on the LNS to get this working please?
Trial and error ends up with a result in the end..... not that I am saying it is working 100% but at least I have the RADIUS assigned address.....
Prefix Delegation needed applying to the SI interface.... As per the below command:
set system services dhcp-local-server dhcpv6 group PD interface si-1/0/0.0
