General Note Regarding the Errata
Please check which printing of the book you have. As we become aware of errors in the book, we add the corrections to the text when we reprint the book. Therefore, not all the errors listed here will appear in all copies.
1/28/08

299Text correction
On the top of page 99, it states that “NAT is covered in Chapter 10, 'Network Address Translation.'”
It should state “Chapter 11”.
2/5/081st & 2nd

3127Text correction
On page 127, near the bottom of the page: “The following table shows you an example host range of two subnets in a Class B 240 (/20) subnet mask:
First subnet 16.0 32.0
Second subnet 31.255 47.255


The table should read:
First subnet16.0 31.255
Second subnet 32.0 47.255
2/5/081st & 2nd

3133Text correction: Missing digit in broadcast address
The third question asks “What subnet and broadcast address is the IP address 172.16.50.10 255.255.224.0 (/19) a member of?” The answer states: “256-224 = 0, 32, 64 (remember, we always start counting at zero(0)). The subnet is 172.16.32.0, and the broadcast must be 172.16.63.25 since 64.0 is the next subnet.”

The answer should state that the “the broadcast must be 172.16.63.255 since 64.0 is the next subnet.”
2/5/081st & 2nd

3138Text correction
Second paragraph under VLSM Design, second sentence: “And if we use a /30 on our WAN links and a /27, /28 and /29 on our LANs, we’ll get 2 hosts per WAN interface, and 30, 14 and 8 hosts per LAN interface – nice!”
Should read: “...we’ll get 2 hosts per WAN interface and 30, 14 and 6 hosts per LAN interface...” since a /29 has 6 usable hosts.
2/5/081st & 2nd

3143Errors in Figure 3.7
The bottom left chart, Class C Network, contains errors.
The IP address in the heading, 192.16.10.0, should read:
192.168.10.0

The Hosts column has incorrect values for Networks A, B, C and D.
Change those values from 12,20,25,4 to 14,30,20,6

The righthand chart also has erroneous IP addresses.
All IPs in the righthand chart should begin 192.168 not 192.16 as printed.
1/29/081st & 2nd

3145Errors in Figure 3.9
The righthand chart contains erroneous IP addresses.
All IPs in the chart should begin 192.168, not 192.16 as printed.

1/28/081st & 2nd

3168Text correction: Answers to Written Lab 3.1, Question 3.
On page 159, in Written Lab 3.1, number 3, we are asked to write the subnet, broadcast address and valid host range for 192.168.100.66/27. The answer on page 168 states “192.168.100.66/27. A /27 is 255.255.255.224. The fourth octet is a block size of 32. Count by 32s until you pass the host address of 66. 0, 32, 64. The host is in the 32 subnet, broadcast address of 63. Valid host range of 33-62.”

The last sentence of the answer on page 168 should read: “Count by 32s until you pass the host address of 66. 0, 32, 64, 96. The host is in the 64 subnet, broadcast address of 95. Valid host range is 65-94.”
2/5/081st & 2nd

3168Text correction: Answers to Written Lab 3.1, Question 10
The last sentence in the answer begins: “The subnet is in the 16.2.0 subnet...”
It should read: “The host is in the 16.2.0 subnet...”
2/5/081st & 2nd

2/6/081st & 2nd

6341Text correction: Error in Figure 6.9
On the left side of the figure the two IP addresses given do not match the interfaces to which they are assigned on the CORP and R1 routers.

10.1.2.0 should go with the S0/0/0 interface, and 10.1.3.0 should go with the S0/0/1 interface, as shown in Table 6.1 on the next page.
9/30/091st

6351Text correction: Incorrect hostnames in sample output
In the first set of output near the top of the page, some lines have the hostname as R2 and some have R3 .

All hostnames in the example should be R2 .

6365Text correction
At the bottom of the page, under Corp(config)#do show ip route lines 7 and 8 contain errors.
Serial0/0/1 and Serial0/0/0 have been reversed.
Serial0/0/1 goes with 10.1.2.0 and Serial0/0/0 goes with 10.1.3.0
5/1/081st

6394Text correction
In the second paragraph after the command output, the first sentence: Notice further down that RIP is routing for directly connected interfaces f0/1 and s0/0/0. contradicts the above output.
The sentence should read:
...directly connected interfaces f0/1 and s0/0/1.
2/6/081st & 2nd

6407Answers to Review Questions, Question 1.
Superflous numbering. There are 5 possible answers, A. through E.
The list should read as follows:

6415Text correction: Answers to Written Lab 6
Answer to question 1.
Add 150 to the end of the route, so the answer reads:

1/28/081st & 2nd

7427Text correction: Error in Figure 7.3
On the left side of the figure the two IP addresses given do not match the interfaces to which they are assigned on the CORP and R1 routers.

11/11/091st, 5th & 6th

7462Text correction: Error in Table 7.4
In the first line of the table, under Description/Function , Shows Hello packets being sent and received on your router

2/6/081st & 2nd

8522Text correction: Incorrectly labeled switches
In the third paragraph, just above the Note, the text reads: “But on our R1 and R2 switches...”
The switches are labeled as S1 and S2 in the example above, so it should read “But on our S1 and S2 switches...”
2/6/081st & 2nd

8529Text correction
In the first paragraph after the table, the second sentence: From the preceding output, you can see that we have five MAC addresses dynamically assigned to EtherChannel poert 1. contradicts the command output in the table above.

10668Answers to Written Lab 10.1
Superfluous numbering. Some answers appear on two lines, but the second line has been numbered, inserting unneded numbers into the sequence and resulting in the appearance of 18 answers for 10 questions.

The list should read as follows:
  1. access-list 10 deny 172.16.0.0 0.0.255.255
    access-list 10 permit any
  2. ip access-group 10 out

  10. show ip interfaces
9/5/071st

11679Text correction: improper range of IP addresses in example
In the first paragraph after the command output, the fourth sentence, which begins: The second answer... contains incorrect IP addresses.

The sentence should read, in its entirety:
The second answer would end up with the exact same result of having only 192.1.2.109 as your inside global, but you can type this in and have it work too: ip nat pool Todd 102.1.2.105 192.1.2.110 netmask 255.255.255.248.

The range 192.1.2.109 through 192.1.2.114 spans two separate /29 subnets
