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. For
example, in the network shown in
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.
Authentication packets of private users in different VPNs do not affect each other.
