Hello. we messed up a problem regarding DNS attribute via RADIUS in BNG IPOE sessions.
The problem is that when radius assigns an attribute: Cisco-AVPair += "primary-dns=8.8.8.8" to an IPOE session, triggered by DHCP, it can be seen in session's attribute list, but BNG doesn't translate this attribute to dhcp offer packet. I've searched a lot and found this note in
"ASR9K BNG RADIUS and COA deployment guide"
-radius attribute for v4 DNS for DHCP triggered IPoE session has not been
supported yet as of 5.2.0, another word, you can download the DNS attribute
from radius server, but BNG will not translate it to DHCP options in the offer
message to the client.
We have nearly the same version - 5.3.4.
After that I've no seen any update regarding this feature, is it supported in any later versions or not.
does anybody here tested this in later major releases or made something differently to work that feature?
Thank you very much.
UPDATE: Nothing changed after XR Upgrade to 6.4.2, still doesnt work.
