I am tasked with configuring two Cisco ASA 5510's as active\standby devices. That task seems relatively straight forward. The question I have is how to split the two ISP's between both devices. I'm thinking that this can be done somehow with a switch between the ISP's and the ASA's, although not sure how. I have an HP procurve 3500yl that I can use for this if its possible. Any suggestions would be greatly appreciated.
