OSPF 실습

어푸어푸🌊 2022. 6. 15. 01:20

RIP 실습본에서 RIP 지우고 OSPF 실행하기.

R01(config-router)#network 192.168.1.254 0.0.0.0 area 0 
(config-router)# network 인터페이스주소 와일드카드마스크 area 영역번호

하나의 area만 설정하기 때문에 와일드카드마스크는 0.0.0.0으로!

 

 

R01 설정

R01(config)#no router rip
R01(config)#exit
R01#sh ip ro
Codes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGP
       D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area

C    1.0.0.0/8 is directly connected, Serial3/0
C    2.0.0.0/8 is directly connected, Serial2/0
C    192.168.1.0/24 is directly connected, FastEthernet0/0
