TACACS aware MPLS VRF

[mirta.majic]

Hello,

we are building MPLS VPN network that includes CE routers with ISDN BRI backup to MPLS VPN core, using L2TP dial-in access. Domain authentication and user authentication for CE routers are done at RADIUS server, through AV pairs which place the CE router in proper VRF.

Question is: could this be achieved with TACACS server as well? Could TACACS server place CE routers in proper VRF? If this is not supported, is there a plan to support it?

Thanks a lot for your help!

Going by what I know, vrf is configured on PE. The CE doesn't have any knowledge of vrf. Am I missing something?
