I am wanting redundancy in a site to site VPN. The central site has a reliable high speed link to the Internet. At the remote site I am looking at either dual PIXs, each going to a separate ISP or an ASA with dual links to separate providers. If I use two PIXs only one would be on at any one time.
Can I at the central site specify two remote peers to the same internal network at the remote site? If that is possible, how long would it take to detect a dead peer and send to the other?
