  • Dear Mike,

    You are trying to ping a link local address and that can be sourced from any address That is why you need to specify the output interface but IOS requires you to type the full interface name and not the shortcut like f0/0.

    Try pinging with FastEthernet0/0 as the interface instead of f0/0

    This should work. If it does not let me know.

  • Thank you Vishal, that was my mistake.

    This is going into the notebook today.

    Cheers

    Mike
