I have two L2 switches that are redundant using spanning tree and I have two ISPs. I would like to put in 2 switches (we'll call them ISW1 and ISW2) capable of running HSRP as well as IP SLA to achieve the following.
ISW1 and ISW2 are running HSRP with a virtual IP which would be the gateway for all my devices on my redundant switches.
ISP A will hook into ISW1 (primary ISP should be used at all costs)
ISB B will hook into ISW2
IP SLA is running which points to ISP A, and if that goes down switches to ISP B
Is it possible to do this type of setup? If so, how would I go about configuring my Routers/Switches with HSRP and routing thenconnect them back to my redundant switches. Basically each switch would have a path to each HSRP device. My internet is delivered via Ethernet from TW Telecom so an actual router isn't really necessary. If anyone could provide a few examples I would greatly appreciate it.
