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 .

Verifier's note: RFC 2328 is not wrong without the stubs links.
However, it does no harm to include them.

This table should be looked at in any future revision of this
RFC.
