[c-nsp] Router memory problem

[Nick Cutting]

We had a case where we used distribute lists matching prefix lists, but some engineers were forgetting the keyword "prefix", so IOS was looking for the ACL, and the ACL did not exist, so all routes were being allowed.

	You should be using a prefix-list,
as it was designed for this type of function.

	distribute-lists (and a bunch of other IOS
crutches) should go away as part of the legacy.

	If you see examples on the internet using them or access-lists to do route filtering, please don't copy those examples.
