load balance between to ISPs

Unanswered Question
Oct 20th, 2009


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.

I have this problem too.

I think that creating 2 tunnels, one for each ISP, and then modifying the routing decisions using route tracking (IP SLA) would be a good solution.

Ex: Make a ping probe to verizon GW, if the ping is OK, you route via verizon tunnel, if 2, or 3 pings fails, then use the other tunnel.
