We have site to site VPN connection to one remote site, from our local router.
Now we have taken one more ISP connection, so my requirement is if one ISP goes down, the traffic has to go through from other ISP.
Can some one provide me the best solution for the same..
1. We have one ISP connection from Verizon
2. Second one is from reliance.
When ever verizon connection fails tunnel need be established automatically from reliance ISP.
