Switch Redundancy for PIX or Router 2800 series in standby configuration

(?) Fairly straight forward, and for the PIX, has a few chapters in the docs describing failover? You need a switch ahead of the PIXs and a switch behind them for the failover.

For the router, you probably are interested in doing HSRP or VRRP for the LAN side. Depends quite a bit for the other side as for your topology.

There's several Cisco SRNDs on HA..

I have searched high and low and couldn't find any document from Cisco except this

If anyone can point to some useful document I'll appreciate
