Aaa For Mpls L3Vpns; Protocols And Standards - HP 6600 Security Configuration Manual

Portal users—Users who must pass portal authentication to access the network.
•
• PPP users—Users who access through PPP.
SSL VPN users—Users who access through SSL VPN.
•
In addition, AAA provides the following services for login users to enhance device security:
Command authorization—Enables the NAS to defer to the authorization server to determine
•
whether a command entered by a login user is permitted, and allows login users to execute only
authorized commands. For more information about command authorization, see Fundamentals
Configuration Guide.
Command accounting—Allows the accounting server to record all commands executed on the
•
device or all authorized commands successfully executed. For more information about command
accounting, see Fundamentals Configuration Guide.
• Level switching authentication—Allows the authentication server to authenticate users who perform
privilege level switching. As long as passing level switching authentication, users can switch their
user privilege levels, without logging out and disconnecting current connections. For more
information about user privilege level switching, see Fundamentals Configuration Guide.
You can configure different AAA methods for different types of users in a domain. See
methods for ISP

AAA for MPLS L3VPNs

In an MPLS L3VPN scenario where clients in different VPNs are centrally authenticated, you can deploy
AAA across VPNs to enable forwarding of RADIUS and HWTACACS packets across MPLS VPNs. With
this feature, the PE at the left side of the MPLS backbone serves as a NAS and transparently delivers the
AAA packets of private users in VPN 1 and VPN 2 to the AAA servers in VPN 3 for centralized
authentication, as shown in
affect each other.

This feature can help a multi-VPN-instance CE to implement portal authentication for VPNs. For more
information about multi-VPN-instance CEs, see MPLS Configuration Guide. For more information about
portal authentication, see "Configuring portal."
