Notes

Notes:

section 2.1.2

Page 20, Figure 2 : A sample Autonomous System.
Two additions have been made to the orginal text which are reflected in the Corrected text.
The last two rows for interfaces Ia and Ib  have been added.
The reason for the same is as explained below.

By definition of point-to-point links under OSPF, for serial interfaces defined by IP addresses, router RT6 should advertise a stub network to Ib whereas router RT10 should advertise a stub network to Ia .
