    ip address bad mask

    realdreams

      Core2(config-if)#ip add 10.16.0.0 255.255.0.0

      Bad mask /16 for address 10.16.0.0

       

      I tried

      ip classless

      ip subnet-zero

       

      But I cannot find them in running config after I enter theses commands. No error message either.

      C3725 12.4(25d)

       

      Why is the router ignoring ip classless and ip subnet-zero?

          ....... i was an idiot....... I put network address as host address and then try to find out why it does not work......

          But seriously tho, the error message is so misleading

           

          BTW

          ip classess

          and

          ip subnet-zero

          are special commands that are enabled by default and does not show up in configuration unless they are explicitly disabled.
