-----BEGIN PGP SIGNED MESSAGE----- Hi Barry,
i have been given the job of setting up failover for a pair of cisco pix 515 i can setup the failover no problems but my question is when the pix fails over does the second one assume the ip address assigned to the interface on the primary or does it use the address assigned under the failover command for that interface.
The failover command assigned an IP address for the interface while the PIX is acting as the standby, or failover. When a fault occurs in the primary, the standby becomes active and assumes all IP addresses and state tables (if configured). A really good explanation is at: http://www.cisco.com/warp/public/110/failover.html
if the interface assumes the address assigned under the failover command how does one go about routing from a router etc to the firewall??
As it assumes the IP address of the primary, all you'd need is something liek a an ethernet switch connecting the outside interface of the two PIX's and the uplink to your border router, etc... When a PIX fails over, it does the usual ARP to tell the switch it now owns the primary IP address.
