*Dynamic Routing Protocol: RIP 하는 법

(rip할때 연결된 네트워크들 다 써줘야함. ex) R1에 바로 옆에 연결된 네트워크가 N1.0과 N2.0이면 -> Network 192.168.1.0

각 라우터에 네트워크 정보가 모두 올라오는지 확인. 시뮬레이션모드에서 RIP 정보를 잡아보기 (auto capture)
show ip protocols

R
S -> 이렇게 Static이 있고 Rip는 없는 경우-> show ip protocols 입력 후 확인-> S를 복사해서 앞에 no [Static 주소] 를 입력해서 삭제하기
(*메트릭 값이 동일한 경우 최대 4개까지 라우팅 테이블에 올라감.(but, 메트릭 값이 작으면 작은거 먼저 올라감)메
ex) fa0/0 x.x.x.x [120/5]
fa0/1 x.x.x.x [120/0] <- 얘가 먼저 올라감)
* passive-interface 확인법
router rip
? <- 여기서 패시브 확인 후
