6th Printing

(applies to this printing and earlier)

Page 24 – Example 2-1, section for router R2 – command network 10.1.222.2 0.0.0.0 should be network 10.1.2.2 0.0.0.0, so it does not match R2’s F0/1 interface.

Page 119 – Step 1, last line on the page – Change “10.16.0.0” to “10.11.0.0”

Page 120 – indented “ip summary-address” command – to the end, add an italicized parameter “admin-distance”.

Page 181 – Figure 6-1 – R3 S0/0/0.2 interface – change the last two octets of the IP address listed by the interface from 23.2 to 23.3.

Page 207 – Figure 6-12 – same edit as for Figure 6-1, page 181.

Page 241 – Table 7-3 – bottom row, right side – the keyword default-metric should instead be default-cost.

Page 342 – command show ip eigrp topo 172.16.104.0/27 – change /27 to /25 (to correct match the route’s prefix length). The output is unchanged.

Page 682 – Chapter 3, Question 1 – correct answer is C (only). Chave first phrase in the explanation to: “Other than the one correct answer,…”.

5th Printing

(applies to this printing and earlier)

Page 15 – Table 1-2 – last row on this page – change “Lifestyle” to “Lifecycle”.

Page 123 – largest paragraph – 8th line – reference to “branch router WAN1” should be “branch router B1”.

Page 144 – Step list – item 4 – the logic in step 4 applies only to network commands whose address ranges overlap. EG, if you configure network 10.1.0.0 0.0.255.255 area 0, followed by network 10.1.1.0 0.0.0.255 area 0, IOS reverses the order of those network commands in the running configuration.

Page 160 – Note at the top of the page – Replace the note with: “The maximum key length is 8 (clear text) or 16 (MD5) characters.”

Page 330 – Question 4 – configuration text in the question – the redistribute command needs an additional keyword match just before keyword external.

Page 391 – first paragraph, first line – ICANN standard for Internet Corporation for Assigned Names and Numbers.

Page 461 – Example 14-1 – on two lines: the very last line, and the last line before the thick black line in the middle of the example – the configuration command ends with extraneous text “… Neighbor 192.168.1.2 remote-as 3”, on both lines. Delete this text on both lines.

Page 551 – The prefix for Unique Local address is literally FC00::/7, not FD00::/8. The book lists FD00::/8 because the 8th bit, per RFC 4193, should always be binary 1, making FD00::/8 true in practice (FD has the 8th bit set to 1). This entry is posted to clarify the point.

Page 682 – Chapter 3, Question 1 – change the correct answer list fo “A and C”

4th Printing

(applies to this printing and earlier)

Page 20 – question 2 – delete phrase “(Choose two answers.)”

Page 32 – last line on the page – change “…is 60 seconds.” to “…is 180 seconds.” The EIGRP Hello timer is 60 seconds in this case, and the Hold timer is 3 X Hello.

Page 118 – 3rd paragraph from the bottom – 2nd line – line begins “10.12.0.0/16” – should be “10.11.0.0/16”.

OSPF’s choice of interfaces from which to take a Router ID only requires the interface be have a line status of up; the book currently states that both line and protocol status must be up. To fix this mistake, make the changes on pages 146 and 156:

Page 146 – steps 2 and 3 – change “up/up” to “up”.

Page 156 – 1st paragraph under heading “Using a Unique OSPF Router-ID” – towards the end of the paragraph – change 2 instances of “up/up” to “up”.

Page 242-243 – Example 7-4 – the seven instances of ip ospf area 34 should be changed as follows: 1) the two instances for R1 need to be ip ospf 1 area 34 . 2) the two instances for R2 need to be ip ospf 2 area 34 . 3) the three instances for R3 need to be ip ospf 3 area 34 .

Page 525 – Table 15-11 – 3rd row from the bottom of the page – change to “The same as the previous item but after applying the outbound filter.”

Page 583 – numbered list, item #1 – the correct command is router-id a.b.c.d, not eigrp router-id a.b.c.d.

Page 584 – Example 17-3 – last line – change eigrp router-id 10.10.34.3 to router-id 10.10.34.3.

Page 681 – Question 2 – Change correct answer to “D”. Delete phrase “working (up/up)” and “A failure of the interface, or” to fix the explanation. In short, the interface state has no impact on whether the interface is listed or not by the show ip eigrp interfaces command.

3rd Printing

(applies to this printing and earlier)

Page 44 – 3rd paragraph – last 2 lines – “…the EIGRP configuration does not have to include…” – starting with this phrase, replace the rest of the paragraph with “…the EIGRP configuration still needs a network command that matches the interface referenced by the neighbor command.”

Page 44 - last sentence, which begins in the middle of the 2nd to last line - replace with "Also note that both routers have a network command that references network 10.0.0.0, and both routers do advertise about subnet 10.10.15.0/29."

Page 45 - in the example - insert a line above both instances of "no auto-summary" - add the line "network 10.0.0.0" in each location.

Page 60 – 3 bullet list – the 2nd bullet isn’t needed. Interfaces referenced by neighbor commands must also have a matching network command, as mentioned in the first bulleted statement. 

Page 75 – EIGRP formula – the listed formula is correct with default K-values. However, if K5 were set to 1 instead of the default of 0, the formula shown would be incorrect. The last fraction, K5/(reliability+K4), would then be multiplied by the result from the rest of the formula, instead of being added.

Page 76 – Last paragraph - 3rd line from the bottom - change “WAN1 also calculated …” to “B1 also calculated …”.

Page 77 – Note in the middle of the page – delete the note. The extended ACL cannot be used in the manner described when used with offset lists.

Page 89 – last paragraph – 3rd line – end of the line – “…is less than…” should be changed to “…is less than or equal to…”

Page 164 – Example 5-8 – section for “router ospf 1” - change “area 0” to “area 1”.

Page 128 – 2nd paragraph – 4th line – middle – a sentence begins “Oddly enough, this command does not actually match interface IP addresses of interfaces, but…” – that statement is not true. The network 0.0.0.0 command actually matches all interfaces. To fix the text, delete the yellowed portion shown here.

Page 131 – Example 4-8 – last line – some printings list “D*”, and some list “*EX”, at the beginning of this line. The text should read “D*”, and the first number in brackets, later in that line, should read “90”. (The printings with “*EX” show that first number in brackets as 170.) Note that the initial characters will be “D*EX”, and the first number in brackets will be “170”, when the router that injects the default into EIGRP does so with the redistribute command (as mentioned at the top of page 128).

Page 139 – question 6 – change answer C to read: “ip ospf md5 whatever-it-is”

Page 149 – Table 5-4 – 6th row, right column – change “225.0.0.6” to “224.0.0.6”.

Page 178 – question 8 – question text – add this sentence to the question: “Only two of the three interface’s costs have been set directly.”

Page 202 – 3rd paragraph – 3rd line – “…that its own priority is 1.” – change 1 to 2.

Page 203 – Figure 6-10 - Change the 2nd instance of “R3 Type 1” to “R4 Type 1”.

Page 237 – Last paragraph – line 1 - change “dual-homed Internet design” to “single multihomed Internet design”. Make same change to page 238, Figure 7-7 caption.

Page 241 – 2nd paragraph – line 1 – after “…area 5.”, add text “ as seen in Figure 7-3.”

Page 249 – last paragraph – replace entire paragraph with: “Configuring NSSA works much like the configuration of stubby areas. For totally NSSA areas, configure area x nssa no-summary instead of area x stub no-summary. For normal NSSA areas, as with stub areas, omit the no-summary keyword. Additionally, normal NSSA areas require that ABRs configure the default-information-originate keyword, making the command on ABRs area x nssa default-information-originate.

Page 264 – Example 8-1 (continued) – change Fa0/0’s IP address to 10.4.4.4 (same mask), and Fa0/1’s IP address to 10.24.1.1 (same mask).

Page 265 – 1st paragraph - 3rd to last line - change “C4” to “C2”.

Page 274 – Table 8-3 – last 2 rows – last column – reverse the “yes” and “no” in these rows. In other words, point-to-multipoint is not Cisco proprietary, and point-to-multipoint nonbroadcast is Cisco proprietary.

Page 296 – Figure 9-5 – The EIGRP topology table on the left should list 11, 12, and 13 instead of 1, 2, and 3; the OSPF topology table on the right should list 1, 2, and 3 instead of 11, 12, and 13.

Page 299 – Figure 9-6 – EIGRP (left) side – top text “Subnet 172.30.7.0/23” should instead be “Subnet 172.30.6.0/23”.

Page 321 – Example 9-13 - above the command redistribute connected subnets, add command area 1 nssa.

Page 330 – Question 3 - Answer C - change “show ip ospf topology” to “show ip ospf database”.

Page 365 – question 6 – answers A and B – add the word “immediately” after the word “fails” in both answers.

Page 369 – Last paragraph - 3rd line - change “show ip route-map” to “show route-map”.

Page 376 – Example 11-4 - last command before end - change “ip local policy PC2-over-low-route” to “ip local policy route-map PC2-over-low-route”. Make the same change, same page, 2nd paragraph, 2nd line.

Page 392 – 2nd to last paragraph - 2nd to last line - change “198.0.0.0/24” to “198.0.0.0/8”.

Page 407 – Example 12-1 – 2nd half (E2 configuration section) – Change 2 instances of “I2-1” to “I1-2”.

Page 531 – question 7 – answer C – the middle of the IPv6 address that reads “FF:FF11” should instead be “FF:FE11”

Page 538 – 1st paragraph – last line – begins “IPv4” – change to “IPv6”.

Page 546 – last paragraph - line 5 – begins with “(RS)” – should be “(RA)”

Page 554 – 3rd paragraph from the bottom – 2nd line from bottom – “…listing B’s MAC address…” should be “...listing R1’s MAC address…”

Page 554 – last paragraph – last sentence, which begins with “This convention allows…” – delete this sentence. It is incorrect because IPv6 uses different multicast MAC addresses than does IPv4. See RFC 2464 for more details.

Page 582 – Step 4 of Configuring EIGRP for IPv6 - change “(where the name matches …“ to ”(where the asn matches …”.

Page 582 – Table 17-5 – 2nd to last row – IPv6 value should be FF02::A, not FF02::10.

Page 610 – Question 9 - Answer D - change “2000::5EFE:C0A5:101 …“ to ”2000::5EFE:C0A8:101 …”.

Page 691 – Answer 3 - 3rd line - change “show ip ospf topology” to “show ip ospf database”.

Page 699 – Answer 7 - 2nd to last line - change “Because C0A5:101 …“ to ”C0A8:101 …”.

2nd Printing

(applies to this printing and earlier)

Page 29 – first line – reference to “10.1.22.0/27” should be “10.1.222.0/27”.

Page 43 – bullet list – 2nd bullet – change to read:

“The key chain name on the two potential neighbors does not have to match.”

Page 43 – bullet list - 3rd bullet: replace with:

“The key number and key string on the two potential neighbors must match.”

Page 45 – 2nd-to-last paragraph – last line – “neighbor 10.10.5.5…” should instead read “neighbor 10.10.15.5…”

Page 73 – Table 3-2 – Line for “Serial” – delay should be 20,000, not 2000.

Page 498 – 2nd bullet list, 1st item – Origin code I indeed identifies routes injected from an IGP, but when redistributed from an IGP, the Origin is “?”. Specifically, replace the text in parenthesis with “using a network command.”

Page 531 – question 8 – command output, last line address reading “FF02::1:FF:12:3456” has 1 too many colons. It should read “FF02::1:FF12:3456”. Make the same change to answer A’s address, and in the answer description in Appendix A, page 697.

Page 536 – Indented IPv6 address that begins “2340” – it is only 7 quartets long. Add to the end the text “:1111” to complete the address.

Page 536 – table 16-2 – the 3rd column should list hexadecimal digits instead of decimal, so replace as follows: 10 with A, 11 with B, 12 with C, 13 with D, 14 with E, and 15 with F.

Page 554 – Table 16-9 – address listed as FF02:1:2: - should be FF02::1:2

Page 554 – last paragraph – the listed solicited node multicast address in incorrect in the 7th quartet. It should instead be “FF02::1:FF00:0/104”.

Page 555 – 2nd bullet in 2 bullet list – the address has an extra unneeded colon. It should instead be “FF02::1:FF7B:5004”.

Page 577 – Figure 17-1 – the right side of the figure was cropped. The complete figure is shown below:

[pic]

Page 681 – Chapter 2, Question 2 – Should list answers B and D, instead of only B.

1st Printing

Page 28 – 1st paragraph – strike the last sentence. It should have referred to R2’s show ip eigrp interfaces command, but that command is not in the example.

Page 34 – paragraph after grayed note – end of 2nd line – command “show ip eigrp interface…” should instead be “show ip eigrp interface detail type number”.

Page 38 – Example 2-5 – middle section, which is the configuration for R2 – the 2nd instance of “no passive-interface Serial0/0/0” should instead read “no passive-interface Serial0/0/1”.

Page 40 – Step 1, 2nd substep – 2nd line, the text reading “the key numbers do not…” – delete the word “not”.

Page 59 – question 9 – The question and answers list 3 occurrences of “200”. Change “200” to “100”.

Page 70 – Figure 3-5 – lower right, step 4’s calculation – it includes an unnecessary “+ 256” in the middle of the formula.

Page 75 – A figure with the EIGRP metric calculation formula is missing from the bottom of the page. Also make sure and note the additional info about this formula in the errata for the 3rd printing of the book.

[pic]

Page 76 – 2nd line – “…Cisco recommends again…” should be “Cisco recommends against…”

Page 93 – First column of row with no text – add text "Could any planned topologies have EIGRP Split Horizon issues?"

Page 123 – large paragraph between the two bullet lists – 2nd to last line – reads “… S0/0/0.1). WAN1 uses…” – replace WAN1 with WAN2.

Page 156 – last line in gray box at the top of the page – “¼” should be simply ¼.

Page 163 – Table 5-8 – last three rows should be considered to have gray highlights, as referenced just before the table.

Page 189 – Example 6-4 – the caption refers to R4; this should refer to R3. The first line of the example lists a prompt with R5; this should also be R3. All command output was taken from R3.

Page 241 – last paragraph – 2nd line – reference to “Type 3 LSAs” should instead list “Type 5 LSAs”.

Page 269 – 2nd paragraph – 4th line – “10.1.1.0/29” should be “10.2.123.0/29”.

Page 269 – 2nd and 3rd paragraphs – These paragraphs reference R1 and R3 as not having a PVC, whereas it is actually R2 and R3 that do not have a PVC. As such, change all 6 references to R1 in these two paragraphs to R2. Also, do so for the similar reference on the last line of the page.

Page 325 – Table 9-7 – 3rd question, 2nd line ends with “…original component metrics?”. Change to “…original metric?”

Page 333 – paragraph after table 10-2 – 4th line – the 2 references to the word “packet” should instead be “route”, because the function is filtering routes, not packets.

Page 341 – 1st paragraph after the Example – 2nd to last line – text “(sequence number 30)” should instead list “(sequence number 10)”.

Page 375 – step 2 – the command is missing formatting to identify parameters and keywords. The correct formatting is: icmp-echo {destination-ip-address | destination-hostname} [source-ip {ip-address | hostname} | source-interface interface-name]

Page 388 – Question 1 – Answer B – change “35” to “30”.

Page 427 – Step List, Step 2 – “update-source ip-address” should instead be “update-source interface-id”.

Page 460 – 2nd paragraph – 4th line – refers to 182.0.0.0/8 near the end of the line – replace with 181.0.0.0/8.

Page 462 – Step List, Step 2 – “update-source ip-address” should instead be “update-source interface-id”.

Page 517 – last paragraph – 2nd line – reference to router “E1” should instead refer to router E2.

Page 531 – Question 7 – answer C should read “FE80::FF:FE11:1111”.

Page 539 – last paragraph, 2nd line – text “…ARIN might assign site prefix…” should state “…ARIN might assign ISP prefix…”

Page 545 – after heading “Stateful DHCP…” - 1st paragraph, 2nd line – phrase “the IP address of the default router,” should be deleted. Stateful DHCPv6 does not supply the default gateway; NDP does.

Page 575 – 5th paragraph – end of 5th line – command “no ipv6 unicast routing” should instead be “no ipv6 unicast-routing”.

Page 600 – Figure 17-4 – IPv6 address – double colons before the last quartet – remove one of the colons.
