RE: [dhcwg] Question about RADIUS Attribute sub-option

[Amy <zhaoyuping at huawei.com>]

Thank you!

I don' know if I catch your mean.

During the lifetime of  a session, some of the RADIUS attributes are not
stable. If we pass these attributes to DHCP Server, we must coordinate state
information between a RADIUS Server and a DHCP server, and there is no such
mechanism now.

Right?

Best Regards!
