I need to add a feature (or license) to a number of my Cisco routers. This can get a bit confusing though, as Cisco made changes to their licensing model when they introduced the ISR G2 series of routers (IE: 1900, 2900 & 3900 series).

These routers use a “universal” image, and you simply license the features you want…in my case the routers are licensed for IPBase and UC, and I need to add the SEC (Security) license to the router. The license tree is pretty simple…

License options for newer Cisco routers

For my older routers, I’m currently running SP Services and I need to add Security/VPN, which means I need to upgrade to Advanced IP Services.

Either way, Cisco is going to get a lot more money from me!!
