Thanks @paul driver thanks for sharing the config.
Here is my complete config . The reason i share this cos i was not that expert on Cisco and XR i just access to weeks ago and it is new . To help other with similar situation i'll have to post all my complete config here.
From following alot of advice and suggestion from good folks in this community @xthuijs i would be ableto compile this complete configuration for PPPoE/DHCP both IPv4/IPv6 to works.
Please note my experience in this journey, the cisco part was easier the only thing was it takes a lot of time to read all the related docs to put together something like this but i believe it is available to anyone in the public to do so. So to avoid anyone from that struggle :) ... i want to put these config here . The much harder part was the Radius Configuration to work with this BNG configure but thanksfully we manage to get that part working. So enjoy
