Dear all,
I am looking at a scenario where I receive frames triple tagged. Wholesaler S-Tag and C-Tag, then our own Service TAG.
To terminate traffic on a a BNG configured node, I am rewriting top 2 tags to 1 tag on a POI, then layer 2 handoff to an ASR BNG, where I end up with a "Rewritten S-tag" and our service tag. There will be several unique S-Tag, but C-Tags are only unique per S-Tag.
Challenge I am facing is how to construct authentication attribute format for BNG ? Option 82 is not feasible in this scenario, so I have to make due with Tags, Sub-IF ids and perhaps a remote ID based on POI where tag rewriting is taking place.
Any suggestions, or pointers will be appreciated.
TIA
/Sam
