Hello,
I am new in BNG and ASR9K topic but with some guideline I configured the device as BNG.
The authentication is via RADIUS, for IPv4 it is working but for IPv6 I have problem, the CPE doesn't get IPv6 address from the selected pool.
I run a lot of debug and found one alert:
DHCPV6 SERVER ERROR: TP3692: dhcpv6_daps_alloc_by_pool: DAPS: daps_ipv6_alloc_by_pool: Failed rc='ip-daps' detected the 'warning' condition 'Warning: Invalid arguments passed'

From RADIUS the BNG got the followings:
default Cleartext-Password := "***********"
Cisco-AVPair = "ip:addr-pool=PPPoE_internet",
Cisco-AVPair += "ip:dns-servers=xx.yy.zz.gg",
Cisco-AVPair += "subscriber:ipv6-enable=1",
Cisco-AVPair += "ipv6:stateful-ipv6-address-pool=v6_framed_pool",
Cisco-AVPair += "ipv6:delegated-ipv6-pool=v6_lan_pool"
Have any of you got the same problem?
Thanks
Tamas
