19일차 RIP,OSPF,EIGRP 재분배

백본만 시스코로 설정한다.
회사정책이 바뀔 경우도 재분배

acl확장인 루프백이 쓰임

@시드(Seed) 메트릭의 사용 / 기본메트릭
외부에서 끌고 들어온 메트릭을 결정해줘야 한다.
메트릭계산을 위한 씨앗

#기본 시드메트릭
RIP 무한대//외부에서 끌고 들어올 떄는 홉카운트를 정한다
EIGRP 무한대//대역폭 딜레이 신뢰도 부하 MTU설정
OSPF 20//E2type으로 기본설정 20.안 적어줘도 된다.

외부에서 끌고온 다른반 애를 위해 설정해줘야 됨

하나의 라우터에서만 재분배

 다수의 라우터에서만 재분배

 

 

 

 

#RIP으로 재분배 설정하기
redistribute rip [process-id] metric metric-value]

각각 경계에 있는 곳에서만 재분배 한다.
rip은 변경되는게 없다.
#OSPF 재분배 명령어
redistribute protocol [process-id] [subnets] [metric-type type-value: E1타입으로 바꾸려면 metric-type 1로 하면된다]
router ospf 1
redistribute eigrp 100 subnets metric-type 1
# EIGRP 재분배 명령어
redistribute protocol [process-id] [metric metric-value]
기본 값들 default-metric 1544 2000 255 1 1500
밴드위드 1544, 열개묶음단위로 묶음 2000*10, 1~255, 1~255,serial네트워크는 MTU 1500byte가 한계
