Managing IP Networks with Cisco Routers
by Scott M. Ballew


Here are the changes that were made in the 4/98 reprint:


(iv) the author's last name (Ballew) was misspelled as "Ballow," and
the editor's last name (Loukides) was misspelled as "Loukades"


{10} part of line 17 should read:

we get 1024 subnets of 16384 hosts each.


(11) para. 3, line -3: Spacing error fixed: "In (too much space)
addition to their own unique..."


{57} In the paragraph that breaks across pps. 56 & 57, the sentence
that reads:

"Routers establish broadcast domains, which are portions of a network
within which a broadcast is seen by all machines."

was changed to:

"Routers establish broadcast domains, which are portions of a network
within which a broadcast is seen by all machines (a single IP network,
in the case of TCP/IP)."


(58) the first paragraph, third line reads:

"... if you replace all of your 4 Mb PS Token ..."

that was changed to:

"... if you replace all of your 4 Mbps Token ..."


{59} the opening question in the second complete paragraph (starts
with "Okay, the broadcast problem is solved...") now reads:

"Okay, the broadcast problem is solved, but how do we allow the hosts
in one broadcast domain to talk to the hosts in another?"


(138, 139: reprinted to accommodate the changes made to 140 and 141)


{140} The code now reads:

router ospf 1
 network 0.0.0.0 255.255.255.255 area 0
! redistribute my static routes with a type-2 external metric of 1
 redistribute static metric 1
! originate a default route if I have one
 default-information originate
!
ip route 0.0.0.0 0.0.0.0 192.168.100.250

Also, the following paragraph was added to the end of the section (top
third of pg 141):

Because I wished to propagate a default route into the OSPF routing
domain, I had to include the <typewriter-text>default-information
originate</typewriter-text> statement in the configuration.  Unlike
RIP, OSPF treats the default route as a special case in the IOS.
Without this additional statement, the default route, regardless of
its source, will not be injected into the OSPF routing domain.  If you
only wish to propagate non-default static routes, you do not need this
statement.


{167} Error in the sample configuration: where the example read
"redistribute igrp 71" and "distribute-list 12 out igrp 71", it now
reads "redistribute eigrp 71" and "distribute-list 12 out eigrp 71".
