Does anyone see this as an Error on page 9-17 of MSPress "70-291"?

    Hello, please open your 70-291 MS Press book to page 9-17 and under
    "Gateway", the following paragraph describes that "the basic concept to
    understand for the gateway value is that this address should be distinct from
    that of the network destination listed in the same routing table entry..."

    Then it gives an example: "For example, in Figure 9-13, the sixth entry
    provides directions to the destination..."

    However, the sixth entry in figure 9-13 looks to me to be pointing to the destination!!

    Am I reading this wrong?? Can anyone make any sense of this example and
    help me out here? I <i>thought</i> I knew routing tables a little better...
    and now I am concerned =\

    Hello again, same poster here: I do see that the 7th through 9th are
    pointing to three distinct host routes (,,
    and but I don't see one entry in the routing table that
    points to!! Am I reading this all wrong??

    I should be rock solid in this, but now I feel like a dummy!! :)

    anyway... the "Gateway" section in 9-17 is really confusing to me. Anyone
    have a better source to explain this concept?

  3. The sixth entry (not including the default route entry). :)

    The entry is the next line.

    Also note, in the 1st edition of the book, (perhaps this is corrected in the
    second edition), the routing table entry is incorrect -- it's indicated as
    host entry (for the gateway host), not a network entry.

    Network Destination Netmask Gateway

    The above entry should be:

    Network Destination Netmask Gateway

    Thanks again Lawrence. You have been a great help to my studies.

    I have the 2nd edition of the book and the 6th entry (not incl. the def
    route) is indeed wrong if I am reading your post right.

    It is:
