Here is a listing of Chapters (with appropriate section nos) from Comer that
will be on the exam:

(1) Chapter 1 (a cursory reading will suffice!)
(2) Chapter 2 (Sections 2.1-2.5)
(3) Chapter 3 (Sections 3.1-3.10)
(4) Chapter 4 (Sections 4.1-4.16, 4.18)
(5) Chapter 5  (Sections 5.1-5.13)
(6) Chapter 6  (Sections 6.1-6.5)
(7) Chapter 7 (Sections 7.1-7.9); just read the IP options - not their    
formats.
(8) Chapter 8 (Sections 8.1-8.12)
(9) Chapter 9 (Section 9.1-9.19); just read the ICMP messages - not
their detailed formats.
(10) Chapter 10 (Sections 10.1-10.15)
(11) Chapter 11 (Sections 11.1-11.12); you don't need to know what
X.25 is; just focus on the TCP/IP and OSI models.
(12) Chapter 12 (Sections 12.1-12.10); I will complete my discussion
on UDP in Thursday's class
(13) Chapter 13 (Sections 13.1-13.18, 13.20, 13.23-13.26, 13.28-13.33);
I will complete my discussion on TCP in Thursday's class.
(14) Chapter 14 (Sections 14.1-14.3, 14.8-14.9, 14.12-14.13); again the
focus is on distance vector and link state routing.
(15) Chapter 16 (Sections 16.1-16.3, 16.9); the focus is on the RIP and
OSPF protocols; you do not need the know the message formats; only
understand the inner workings of these two protocols.

My lecture notes (Lectures 1-6) will supplement the material covered
in these sections of Comer.
