We have two VPN SPA modules on the different cisco 6500 Routers(12.2(18)SXF. We set up IPsec failover with HSRP and SSP. I think the failover would be oocured when I will upgrade IOS of 6500 and reboot. I wish the original primary SPA could keep active when it is online.But I did not find any priority parameters about failover. My question is do I need force it to become active from standby status like FWSM settings or add "standby priority..." on the configuration of module interface?
During an HSRP and IPsec failover, SSP transfers IPsec and ISAKMP SA state information between the active and standby switches, allowing existing VPN connections to be maintained after a switch failover. The standby preempt command is required, and should be configured with no priority or delay options.
