I'm looking at Interesting Parameters for flap dampening and I don't know how to write the ACL. How do you write an access list to ignore the network and only look at a range of mask bits?

Robert: The 'discussion' of Jack's report seems to have overwhelmed an actual operational question. I am shocked and surprised. In cisco parlance, such an entry might be access-list 142 deny ip any 255.255.255.128 0.0.0.127 which blocks any prefix longer than a /24. As to how to express the dampening in the report you mention, could someone who has it actually installed (come on RV, SD, ...) and debugged please post? I have exceeded my error quota for the day. Thanks. randy
