Redundant VPN design

I am planning to implement a Cisco 2801 and a Cisco 3640 at Corporate. Keep in mind both routers have a T1. I also have over 30 sites which will have Cisco 1801s.

My plans is to implement at corporate GLBP for redundancy for internet and load balancing. How would I do redundancy for the VPN tunnels being terminated at Corporate?

It is to my understanding for GLBP to work I will need IOS 12.2T, but will this IOS release also allow me for redundant VPN?

Hi

I dont think in adjacent with GLBP you wont be able to have reduandcy for your VPN though you will have the reduandcy for your equipment/link in the central location with that.

Have a look at the Cisco press book `IPSec VPN Design' ISBN 1-58705-111-7, goes into this in quite some detail.

Although the book doesnt cover GLBP, I think you will still find it very useful.
