Question Regarding Cisco ISR routers supporting IPsec VPN tunnels

[siamak1]

What's the difference between CISCO2911-SEC/K9 and CISCO2911/K9?

I know that CISCO2911-SEC/K9 supports 225 simultaneous IPsec tunnels and has to be upgraded to CISCO2911-HSEC/K9 to support more than 225 tunnels.

But what's the limit on CISCO2911/K9 with regards to simultaneous IPsec tunnels?
