Before I get too far down the road only to find out I'm off target, can anybody comment on the viability of configuring an NRP module on a 6400 to act as a VPN concentrator ?
I'm hoping to be able to configure the NRP as a terminator for L2TP connections from Microsoft VPN clients, and then stick them into the appropriate VRF.
RADIUS or TACACS would be preferrable as the authentication mechanism but not essential.
