My un-educated answer: it depends. If the BGP route is the next hop from the machine sending the ping, then yes, you'll probably need to restart. The ping instance will continue to want to use the broken path as its next hop. If, however, you're downstream from the BGP route (another hop between you and the BGP router) it shouldn't matter because your machine's next hop wouldn't change. Does that describe the behavior you're seeing? Brian
