Discontiguous address ranges in a NAT pool. (Question #38)

Consider the situation where you want to use the 172.16.1.0/24 addresses
in a NAT pool with the constraint that the subrange starting from the
address 172.16.1.42 and ending with the address 172.16.1.88 not be used
for NAT translations. How would you accomplish the task?

Comments:
I had to check the Cisco site but here is the answer I found.

!
ip nat pool users_A prefix-length 24
address 172.16.1.1 172.16.1.41
address 172.16.1.89 172.16.1.254
!
 
Yes, that is the right answer.
