RouteFlap performs route flap analysis and stastics collection on the machine parseable output generated by route_btoa.

Synopsis

routeflap ascii_input_file

Description

Steps to performing toute flap analysis:

  1. sbgp -vo /tmp/binary_data enss131.t3.ans.net AS690
  2. wait a for 24 hours, or whatever
  3. route_btoa -mi /tmp/binary_data > /tmp/data
  4. routeflap /tmp/data

RouteFlap produces generates output of the form:
