Data Encryption over leased lines

Hi Leo,

Thanks for ur reply.

  Above example is using internet cloud, but i'm having point to point Leased lines using serial & BRI interfaces.

I don't have tunnel interface.

And also one more question how many crypto map sequence number can be supported by cisco 3925 router(Central site).

If i created 50 sequence no is there any memory or processor issue will be raised?

Thanks

50 GRE tunnels is nothing.  What I'd like to know is what is the total bandwidth to your head office and whether or not your router has built-in Encryption module.

Personally I would use GETVPN. It was designed for encrpyting over MPLS, but it works equally well over point-to-point circuits. It scales very well, I've had 30+ sites.
