Hi All
Suppose I have a network topology shown as below.
CPE device have establish One PPPoA connection with NAS. NAS can do
authentication for PPP user Using PAP, CHAP protocol, NAS may use
RADIUS
server to authenticate the PPP user.
If NAS supports IPv6 RADIUS attributes, User specific prefix
Can be get from RADIUS server for this PPP client at the time of
authentication. Now NAS can send prefix get from AAA (RADIUS) in RA
message to CPE.
NAS can also advertise its own interface prefix to CPE device.
What is the benefit of advertising prefix taking from AAA to CPE
Device?
Does CPE device use this prefix only for auto-configuration its PPPoA
Interface?
If CPE Device does not support DHCP6 Client, how it should support
auto configuration of its internal sub-networks?
PPPoA
User-------CPE----(ATM)---NAS (IPv6 AAA-with RADIUS Support)
