Portal Authentication Across Vpns; Portal Configuration Task List - HP 3600 v2 Series Configuration Manual

Secondary: Indicates that the user logs in from the peer device, and the user data is synchronized
•
from the peer device to the local device. The local device is in synchronization state. It only receives
and processes the synchronization messages and does not process packets from the server.

Portal authentication across VPNs

This feature is not applicable to VPNs with overlapping address spaces.
In a scenario where the branches belong to different VPNs that are isolated from each other and all
portal users in the branches need to be authenticated by the server at the headquarters, you can deploy
portal authentication across MPLS VPNs. As shown in
clients serves as the NAS. The NAS is configured with portal authentication and AAA authentication,
both of which support authentication across VPNs. The NAS can transmit a client's portal authentication
packets in a VPN transparently through the MPLS backbone to the servers in another VPN. This feature
implements centralized client authentication across different VPNs while ensuring the separation of
packets of the different VPNs.

Portal authentication configured on MCE devices can also support authentication across VPNs. For
information about MCE, see Layer 3 - IP Routing Configuration Guide.
