Printed	Page 54 figure 3.3 network diagram	The given IPs for the serial point-to-point connection are given as 192.168.30.2 and 192.168.30.3. These seem to be an odd choice given such connection are typically a /30 mask which would yield usable IPs of 30.1 and 30.2 The given scheme would require a /29 mask which while not necessarily wrong it as mentioned seems odd for the given schematic.

Printed	Page 56 top of page	The point-to-point serial connection described in figure 3.3 on page 54 gives IPs of 192.168.30.2 and 192.168.30.3 for the point-to-point serial connection between Org A and Router X. This scheme would require a /29 mask yielding 30.0 - network address assuming ip subnet-zero is in use. 30.1-30.6 as usable host IPs 30.7 - broadcast IP The line of the access-list that is supposed to permit access to this link is access-list 2 permit 192.168.30.2 0.0.0.1 This would be incorrect for a /29 network which would be written access-list 2 permit 192.168.30.0 0.0.0.7 Moreover it's likely that the IP addresses for this serial link should be 192.168.30.1 and 30.2 (/30 subnet) which would have an access list statement of access-list 2 permit 192.168.30.0 0.0.0.3 thus permitting IPs of 192.168.30.0 - 192.168.30.3	Anonymous
