Bob,
I don't have this book yet, so my first question would be; what are
the primary requirements for this lab?. In having casually browsed through
the book I believe being able to ping all interfaces was one major
requirements of those labs. The key is as long as you followed those
guidelines then anything they didn't say is fair game.:->
HTH
