Spelling: RouteFlapping
A flapping router is a router that transmits routing updates that
first advertises a destination network via one route, then a different
route. This behavior is called route flapping.
It is caused by conditions such as hardware, software and
configuration errors, as well as unreliable connections -- like our
dodgy wireless links, which drop out intermittantly.
Route flapping is bad, because it increases latency and processor
usage on our routing machines -- often a packet in transit will be
held at a router while it recalculates which route it should take.
Efforts have been made to allieviate this problem in BGP [1], you can
find more information at FlapDampening [2].
