A unicast routeing daemon e.g. routed, gated etc. is running on a FreeBSD 3.x router. A new route is installed by a process running with root privileges (or by a user with root privileges using route command ) into the kernels forwarding table. What happens (if anything) to notify the unicast routeing daemon that a new route (which the daemon will likely advertise to rest of network) has been installed ? Does the kernel immediately send a notification on a routing socket to the routing daemon when the new route is installed in the kernels forwarding table ? Or does the routing daemon need to poll/scan the kernel's forwarding table periodically to spot any newly installed routes or modified routes ?
