Dual Site-to-site VPN links

Unanswered Question

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?

You want to create aback up L2L connection,

So just add in the crypto map the ip address of PIX-2

(Central site)

crypto map mymap VPN

set peer ------ PIX1

set peer ------PIX2

So the VPN tunnel will use the first ip in the crypto map .if the first ip failed (detecting via DPD) the ASA will use the second IP.
