Chapter 1 . Second paragraph of page 25

Hi,

Chapter 1, page 25:

"
For example,
given the current size of a full Internet routing table is about 420,000 IPv4 prefixes,
the MX5 would be able to handle over nine full Internet routing tables.
"

The number of the DFZ routes should be updated.

Congrats on the new edition!

The test in question describes the previous code example. The text in the 4th line references ae5.2000 but it should be ae5.200 according to the example.

Best,

1st paragraph

It looks like the author(s) used the interface numbering from the previous example rather than the current example. They say "... if a frame arrived with a single tag of 200, IFL ae5.2000 would accept it". I believe they meant to specify interface ae5.200 rather ae5.2000. The native VLAN example configuration doesnt define the ae5.2000 interface but the previous example does.

Thanks - Jon

Warning/Caution paragraph

"Had the operator not included the protocol tcp condition along with a port value in the telnet_out filter..." should state "Had the operator not included the protocol tcp condition along with a port value in the tcp_out filter".

Chapter Review Question N.5

The Review Question N.5 of the Chapter 6 doesn't contain the correct value (31).
A. 26
B. 27
C. 33 <-- should be 31
D. 34

Also the Review Answer on the next page contain correct formula with wrong final value:

the book =
5. Answer: C.
Recall that the global FPC number = (member-id * 12) + local FPC. In this case, the answer would be (2 * 12) + 7 = 33.

should be =
5. Answer: C.
Recall that the global FPC number = (member-id * 12) + local FPC. In this case, the answer would be (2 * 12) + 7 = 31.

Figure 8-19

The network 10.8.0.4/31 is assigned to the link between R1 and R3 but both the ip address in the interfaces in the figure are from subnet 10.8.0.0/31.

R1 (xe-2/1/0.0) has .0 but should have .4
R2 (xe-2/1/0.0) has .1 but should have .5

Also the code at the end of the page indicate .4 and .5
