Setting up a Juniper (MX104) to assign IPv6 IA_NA addresses

I'm having difficulty getting a Juniper which is acting as an LNS to assign IPv6 addresses via IA_NA

I've setup multiple pools on the Juniper as described on the Juniper websites as follows:

set access address-assignment neighbor-discovery-router-advertisement IAPD-PPPOA-POOL set access address-assignment pool delegated-pool family inet6 prefix 2a02:123:c05e::/56 set access address-assignment pool delegated-pool family inet6 range d1 prefix-length 64 set access address-assignment pool IAPD-PPPOA-POOL family inet6 prefix 2a02:123:c05d::/48 set access address-assignment pool IAPD-PPPOA-POOL family inet6 range IAPD-RANGE low 2a02:123:c05d:1::/64 set access address-assignment pool IAPD-PPPOA-POOL family inet6 range IAPD-RANGE high 2a02:123:c05d:ffff::/64 set access address-assignment pool v6-ia-na-pool family inet6 prefix 2a02:123:c05f:1000:0000::/64 set access address-assignment pool v6-ia-na-pool family inet6 range v6-range-0 low 2a02:123:c05f:1000::1/128 set access address-assignment pool v6-ia-na-pool family inet6 range v6-range-0 high 2a02:123:c05f:1000::ffff:ffff/128 

but no luck.

I think it's probably as I've defined the v6-oa-na-pool but there is no reference to it anywhere to use this pool for IA-NA assignment.

The things is if I look at the Juniper site it also doesn't have details of where it should be referenced. I'm obviously missing something here
