Hi all,
from IOS XR Release 6.4.1 Cisco introduce option on BNG to force clients to reauthenticate on dhcp renew or rebind, because before the AAA server was checked for the authetication and authorization only when client sent boadcast dhcp discover for server ( IPoE subscriber case).
As described here : https://www.cisco.com/c/en/us/td/docs/routers/asr9000/software/asr9k-r6-4/bng/configuration/guide/b-bng-cg-asr9000-64x/b-bng-cg-asr9000-64x_chapter_0101.html#id_65538
we tried this feature on BNG as DHCP server work perfectly, but in our case we use BNG ASR9K Release 6.6.3 as DHCP PROXY.
the clients are not forced to get new policy and new authorization profile on dhcp renew or rebind.
did someone know how to resolve this problem ?
