Hii ..

I need some guidance on Get VPN .GetVPN is supposed to be the latest VPN solution for organistaion connected though MPLS VPN services.The Get VPN solution with MPLS VPN is straight forward but in a enterprise where the ISDN remote access is deployed how the KEY exchange process completes as the key server is not the one directly rechable while an isdn call is getting connected.It would be really helpfull if some one can share some ideas.

Thanks & Regards,

ISDN provider edge router dial-in access to an MPLS VPN, a network access server functions as both network access server and provider edge router. (For that reason, the network access server is referred to here as a network access server/provider edge router). In contrast to an L2TP dial-in access session, the PPP session is placed directly in the appropriate VRF for the MPLS VPN, rather than being forwarded to a network concentrator by a tunneling protocol. Direct dial-in is implemented only with pure ISDN calls, not analog calls. Direct dial-in can also include MLP, Multichassis MLP (MMP) or address management, as previously described in the L2TP Dial-In Remote Access section.
