Hi,
when "split-horizon simple" is used, ripd might send out messges with 0
routes in it. This is because nentries is counted up even if the route
was not added to buf. Moving nentries++ up is fixing this.
Below log message is an indicator for this bug:
recv_response: bad packet size, interface vether0
OK?
