David,
Here is another answer, to your question about the wildcard format. It
depends, are you excepting routes more specific than 140.1.0.0 or not. If
your answer is not, use the 0.0.0.0 wildcard and be done with it. If you
will be excepting more specific routes use the 0.0.255.255 wildcard.

It is alittle more than that.
The three address all have a different first octet. 140 141 and 142
This wasn't taken into consideration in any of the responses.
The simplest way to handle it maybe to specify the 3 address seperately.

Actually it should be:
access-list 1 deny 140.0.0.0 0.0.255.255
access-list 1 permit 140.0.0.0 0.3.255.255
He only wanted 1, 2 and 3.

Guys
If u are asked to allow say 3 routes (140.1.0.0,
141.2.0.0 & 142.3.0.0) in to your rack from a
backbone. What type of wildcard would you use in ur
ACL. Would the following be the best?
access-list 1 permit 140.1.0.0 0.0.0.0
access-list 1 permit 141.2.0.0 0.0.0.0
access-list 1 permit 142.3.0.0 0.0.0.0
OR:
access-list 1 permit 140.1.0.0 0.0.255.255
access-list 1 permit 141.2.0.0 0.0.255.255
access-list 1 permit 142.3.0.0 0.0.255.255
?
Thanks
