Hello Aulfat,

Indeed the IOS (that's how we call the Cisco firmware) needs to be upgraded in your case. For 1841 model, the IS-IS is supported in the Advanced Security, Advanced IP Services or Advanced Enterprise Services feature set of the IOS. Personally, I recommend the Advanced IP Services.

Best regards,
