In addition to my earlier post, you are missing the ID for the ia-pd association.

replace:

id-assoc pd {

with:

id-assoc pd 0 {

and you are referencing your upstream interface instead of your downstream interface in the delegated prefix-interface statement.

replace:

prefix-interface re0 {

with

prefix-interface re1 {


Thanks,
Tom
