Section 3.4 says:

                   Destination   RT3 adv.   RT4 adv.

              Table 6: Destinations advertised into Area 1
                        by Routers RT3 and RT4.

It should say:

                   Destination   RT3 adv.   RT4 adv.

              Table 6: Destinations advertised into Area 1
                        by Routers RT3 and RT4.

Notes:

The distance from RT4 to N8 should be changed from 18 to 25. Unless there is a virtual link between RT7 and RT10, the shortest path from RT4 to N8 is 25, not 18. Although a virtual link from RT7 and RT10 is discussed in the last paragraph of Section 3.4, it is not assume part of the network design. Moreover, this change is needed to make the N9-N11,H1 row consistent with the N8 row, as each entry in the N9-N11,H1 row must be 11 greater than the same-column entry in the N8 row.
