From a core Layer 3 switch I have got two routes to the Internet via two different service providers who provide their own routers (Which i have no access to).
I have two routes as if I were to have a single line, I would pretty much saturate the firewall CPU between the router and core switch.
The scenario as it stands is, every time router02 fails (exclusively used to web traffic), i have to quickly telnet to the core switch and reroute the default route to firewall01 which is for router01.
I have to do this remotely and have to wait for my ITcontact at the office to reboot router02 before I can reroute traffic back to firewall02.
Now the question is, how can I automate this procedure? what protocols are there to automate this?
Basically I want to automate the change of default route's next hop address when the current next hop is down. (Routing to firewall PIX)
I know this may seem easy enough but because I'm working with pix firewall devices as my next hop i'm not too familiar with possible methods.
Please have a look at the attached picture to give a better understanding of the problem.
Kind Regards :)
