For some reasons you end up with two prefixes in the RIB that are indistinguishable. The decision process should in any case find a more prefered route or it will fatal with the given message. Currently I know only one way to produce this by announcing a network twice, once via config file and the other is added via bgpctl. Normaly it will "crash" right after you entered the bgpctl command (bgpctl network add 10.10.0.0/16) and a restart of bgpd will solve the problem until you reenter the network via bgpctl. If this is not the case I need your bgpd.conf file and probably some bgpctl output (for the beginning a "bgpctl show" before the server crashes would be good). I will try to fix the problem with announcing a network twice till next week. -- :wq Claudio
