3 127 Text 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

3 133 Subnetting in Your Head: Class B Addresses
Answer to third question (line 17 on the page, not including heading) reads in part: "...the broadcast must be 172.16.63.25 since..."
It should be "172.16.63.255"

3 138 Text 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.

3 143 Errors 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.
1/29/08 1st
3 145 Errors 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.

At the top of the page, the last bullet point contradicts Figure 3.16.

3 168 Answers to Written Lab 3.1
Answer to Question #3:
The third sentence, which begins "0,32,64." should read:

3 169 Answers to Written Lab 3.3

5 285 Error in Table 5.5
The Description for "Platform" (line 5 in the table) is incorrect.
It should read:
"The type of Cisco device directly connected. In the previous output, the Corp router is directly connected to a 1242 Access point, a Cisco 2801 and two 1841 routers."
2/6/08 1st
6 341 Text 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.
9/30/09 1st
6 394 Text 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."
2/6/08 1st
6 407 Answers to Review Questions, Question 1.
Superflous numbering. There are 5 possible answers, A. through E.
The list should read as follows:
  1. Gateway(config)#ip route ...
  2. Gateway(config)#router rip
    Gateway(config-router)#network 206...
  3. Gateway(config)#router rip
    Gateway(config-router)#network 206...
  4. Gateway(config)#ip route 206...
  5. Gateway(config)#ip def...

6 415 Text correction: Answers to Written Lab 6
Answer to question 1.
Add " 150" to the end of the route, so the answer reads:
"1. ip route 172.16.10.0 255.255.255.0 172.16.20.1 150"
1/28/08 1st
7 427 Text 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.

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.
11/11/09 1st
7 462 Text 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"
should read:
"Shows Hello packets being received on your router."
2/6/08 1st
8 522 Text 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...”
2/6/08 1st
8 529 Text 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.
The sentence hould read:
"...you can see that we have seven MAC addresses..."

8 548 Incorrect Answer to Review Question 5.
The correct answer is "C. To prevent switching loops in networks with redundant switched paths."

The explanation is correct.

10 668 Answers 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
  3. access-list 10 deny host 192.168.15.5
    access-list 10 permit any
  4. show access-lists
  5. show running-config
    sh ip interface
  6. access-list 110 deny tcp host
    172.16.10.1 host 172.16.30.5 eq 23
    access-list 110 permit ip any any
  7. line vty 0 4
    access-class 110 in
  8. ip access-list standard No172Net
    deny 172.16.0.0 0.0.255.255
    permit any
  9. ip access-group No172Net out
  10. show ip interfaces

11 679 Text 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

12 735 Text correction: Incorrect information in explanation for the answer to Review Questions 2. and 4.
In the explanations for the answers to Review Questions 2. and 4., the IEEE wiring standard 802.11b is mentioned twice. In both instances, it should read:
""The IEEE 802.11b and IEEE 802.11g standards"
11/11/09 1st and 2nd
13 770 Review Questions: Error in Question 11
