3/30 5주차 : RIP와 Passive interface

hayoung.dev 2021. 4. 19. 03:51

[RIP]

RIP는 사람이 직접 설정하지 않아도 알아서 라우터를 자신들끼리 주고받는다.

RIP의 단점은 속도가 느려진다. 그래서 홉 계수를 15로 제한한다.

16은 무한대로 간주되고 도달할 수 없는 네트워크가 된다.

1. PC와 Switch끼리는 전부 1/0/1로 연결

2. Switch 간에는 구성도와 같이 연결

3. R1 CLI 설정

Switch>enable
Switch#config t
Enter configuration commands, one per line.  End with CNTL/Z.
Switch(config)#hostname R1
