gt = greater than so gt /23 = subnets with a mask of above /23. lt = less than so lt /17 = subnets with a mask less than /17.
so using prefix lists can you give me an answer which would do the following:- 1. Deny subnets of class B networks 2. Deny supernets of Class C networks 3. Deny networks starting 193.x.x.x 4. permit all else. For the 1st one ask yourself what makes a class B network a Class B network? From this you will find out what your /x prefix should be. Then what mask = subnets of a class B network gt or lt. and so on -----Original Message----- From: dk [mailto:[EMAIL PROTECTED]] Sent: 04 February 2002 12:07 To: [EMAIL PROTECTED] Subject: prefix lists ..
