Hej
I have attached logs from BNG, DHCPv6 Client and Radius
We have ASR9903 IoSXR 24.2.1. We are trying a BNG setup where we get Radius to assign IP address and Default route.
What we are having problem is that we can not seem to send Default Route to DHCP IPv6 Client.
We are trying Framed-IPv6-Route to push default route (and some others for test purposes). We see the BNG device is recognizing the radius attribute Framed-IPv6-Route but it does not send it to DHCP client.
But when I check the DHCP client it only has /128 address and no default route

Gateway of last resort is not set
L 101:101::105/128 is directly connected,

If I check BNG, it seems to get the attribute from Radius, but doesn't send it to DHCP client for some reason
