Open Shortest Path First OSPF Routing Protocol – آموزش پروتکل مسیریابی

پروتکل قدرتمند و پرطرفدار OSPF یا Open Shortest Path First، پروتکلی Link State و Open Standard است که در RFC 2328 شرح داده شده است. این پروتکل برای پیدا کردن Neighbor – یا در واقع روترهای متصل به خود – از Hello Message استفاده میکند. پیام Hello به آدرس Multicast 224.0.0.5 (AllSPFRouters) ارسال میگردد اگر در رسانه ای خاص Multicast قابل استفاده نباشد، از Unicast استفاده میکند…
