Your IOS image does not have the ISIS protocol in it. Off hand not sure which one for your particular model, but that's what the error is referring to.

I can see that protocol is supported since i am getting this output

R1(config)#router ?

bgp Border Gateway Protocol (BGP)


Enhanced Interior Gateway Routing Protocol (EIGRP)

isis ISO IS-IS

iso-igrp IGRP for OSI networks

mobile Mobile routes

odr On Demand stub Routes

ospf Open Shortest Path First (OSPF)

rip Routing Information Protocol (RIP)
