What I am wondering about is if there is a way to load balance 2 VPN tunnels as one.. The picture below shows my situation... I have a site with 1 ISP that has a 2821 router, and a 2nd site with 2 different ISPs with a cisco 1841 router. I am wondering if I can establish 2 seperate tunnels between the devices, and then somehow loadbalance traffic over the 2 seperate tunnels? The reason I want to set this up is because the ISP3 in the picture below is much better than ISP1 and 2 and we are maxed out with ISP1 and 2 as far as bandwidth goes.
I am not interested in purchasing a seperate piece of equipment to handle the VPN load balancing... Just wondering if it is possible with the Ciscos we have?
If that does not work out, then I am planning on establishing the 2 VPN tunnels, and sending some of our traffic through 1 tunnel, and the rest through the 2nd tunnel.. If you know of any problems with that type of setup, please feel free to let me know..
Appreciate any help you can provide!
