I am using cisco packet tracer 7.0. I am supposed to set isis as the routing protocol. But when try to do this in config mode, the router does not identify the command "router isis". When I enter router ? the following is shown:

  Router(config)#router ?

  bgp    Border Gateway Protocol (BGP)

  eigrp  Enhanced Interior Gateway Routing Protocol (EIGRP)

  ospf   Open Shortest Path First (OSPF)

  rip    Routing Information Protocol (RIP)

There is no isis here.

Can anyone help me?
