We are adding a new 6509 switch B to use for redundancy of current 6509 switch A using HSRP. Currently, we have 2 ASA firewall units configured as active/standby failover single mode. Both ASA units connects to switch A at this time. We are planning to relocate the connection of ASA standby unit to the new 6509 switch B. What would be the best way to configure the ASA units for redundancy if switch A fails and traffic goes thru switch B. Will the ASA standby unit automatically start passing trying? Please advice.
