Page 333-334 Table 10-2 and 10-3 are not labeled. Delete this from errata.
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 145 – 3rd paragraph – 2nd line – change S0/0/0 to S0/0/1.
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 290 – Question 5 – In the question, change 10.0.0.0 to 10.1.1.0.
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 411 – Figure 12-13 – For ISP2, change “ASN 1” to “ASN 2” (two instances).
Make the same change to the top of figure 12-15, page 413.
Page 535 – paragraph beneath Figure 16-1 – 3rd line from the end – change “NAISP2” at the end of a sentence to “NA-ISP1”.
Page 576 – 2nd to last paragraph – change 2 instances of 2003:… to 2013:…
Page 682 – Chapter 3, Question 1 – correct answer is C (only). Change the first
phrase in the explanation to: “Other than the one correct answer,…”.
Page 683 – Chapter 3, Question 3 – Correct answer is A (only). The explanation is
correct as is.
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.

Last Updated: August 8, 2014
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 584 – Example 17-3 – last line – change router-id 10.10.34.3 to eigrp
router-id 10.10.34.3.
Page 651 – Figure 19-1 is missing three (Ethernet) lines; add lines on the bottom
right, between: BO1 and SW1, SW1 and SW2, and between BO2 and SW2.
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 73.”
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 pointto-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

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,
