  4. Subject: [PATCH] topotests: add bgp route reflector scenario
  5.  
  6. that scenario involves 2 route reflector servers, replicating the same
  7. route to a route reflector client, named r1. the goal is to check there
  8. is no flapping when one route reflector server leaves, as the other
  9. remaing present.
