Hi, My understanding of the routing table updation by the routing command is like this. Any user requests to add or delete a route is stored in the rt_msghdr structure & written to the routing socket. The route_output() of the kernel does the updation by calling appropriate functions. It also sends the same message to all processes that have open a routing socket for listening. Is my understanding correct? Kindly mail me if anything that i have said is incorrect. regards ravi prasad __________________________________________________________________ Get your own FREE, personal Netscape Webmail account today at http://webmail.netscape.com/ To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-net" in the body of the message
