Despite our concerted effort, we found that it is difficult to avoid inadvertent typos in a book of 800+ pages. As we like to say: every technical book must have an errata list:-) Here's our collection so far. If you find any, please let us know.

*p. 49: line 11: Replace j=3 by j=5; now, S becomes {1, 2, 4, 5}. Consequently, set S in last two rows in Table 2.4 on p. 48 changes. At iteration-4, S is {1, 2, 4, 5}, at iteration-5, S is {1, 2, 4, 5, 3}. Also, B13 in iteration-4 and iteration-5 changes to 20, and Path to 1-4-5-3.

*p. 49: line 15: change 'Bellman-Ford' to 'Distance-Vector'.

*p. 54: line 8: Bandwidth of link 3-6 is missing. Use 3 as its bandwidth.

p. 113: Eqn (4.2.4): (correction is marked in bold, italics)
x12* = h,       x132* = 0,           when 0 <= h <= 10
x12* = 10,     x132* = h-10,       when h >= 10 and h <= 20.

p. 113: Eqn (4.2.5): (correction is marked in bold, italics)
x12* = 0,          x132* = h,           when 0 <= h <= 10
x12* = h - 10,     x132* = 10,       when h >= 10 and h <= 20.

*p. 169: Read last three lines, continuing to the top of the next page as follows (with corrected router identifiers corresponding to Figure 6.1):
Here, Area 3 is connected to the backbone area using transit Area 2 through a virtual link that connects router R5 to router R13. Also note that if the link between routers R2 and R4 in the backbone area goes down, Area 0 becomes partitioned; to avoid that, a virtual link between Area-Border Routers R6 and R8 is established through Area 1.

p. 246: Figure 8.3: IP address with interface s1 should be 10.6.17.5

p. 248: Figure 8.5: In AS65222, N8 (with 172.32.0.0/16) should be N12

p. 394: Figure 12.9: DPC for the IAM message on the right should be 1.4.3 (NOT 1.4.4)
