Section: 10.2

Original Text
-------------
1-Way
    An Hello packet has been received from the neighbor, in
    which the router is not mentioned.  This indicates that
    communication with the neighbor is not bidirectional.

Corrected Text
--------------
1-WayReceived
    An Hello packet has been received from the neighbor, in
    which the router is not mentioned.  This indicates that
    communication with the neighbor is not bidirectional.

Notes
-----
RFC2328 defines The Neighbor state machine and it's states. One of the states is defined/named as 1-WayReceived ([Page 95] 10.3.).
1-WayReceived is also mentioned on page 84 and 98.

Pages 85 and 88 use event 1Way which should be renamed to 1-WayReceived for consistency with definition of the state.

[Page 85]
Event 1-Way forces Init state,

[Page 88]
10.2.  Events causing neighbor state changes 
1-Way
    An Hello packet has been received from the neighbor, in
    which the router is not mentioned.  This indicates that
    communication with the neighbor is not bidirectional.

On p. 85 after Figure 13, it says "Figure 13: Neighbor state changes (Database Exchange)
 ....
                Event 1-Way forces Init state,
 "
and Event 1-Way should be replaced with 1-WayReceived
