การคอนฟกส OSPF บน UBNT EDGE ROUTER

ตวอยางเนตเวรคคอนฟกส

ไดอะแกรมประดวย 3 เราเตอรทตองการคอนฟกสเราใหเปนแบบ OSPF


ตงคาเราเตอร (R1)

ตงคา IP addresses.

ubnt@R1#set interfaces ethernet eth1 address 10.0.50.1/24

ตงคา OSPF.

ubnt@R1#set protocols ospf parameters router-id 10.0.50.1

ubnt@R1#set protocols ospf area 0.0.0.0 network 10.0.50.0/24





ตงคา OSPF.

หลงจากตงคาคอนฟกสแลวท ากรตรวจสอบการเราวาถงกนหรอไม เราเตอร R1 จะเรยนรเนตเวรค 10.0.60.0/24 เนตจะเราไปถงโดย 10.0.50.2
