EIGRP 실습

물리랩

 

- frame-relay 설정(no splite-horizen으로 라우팅 프로토콜 사용.)

- eigrp 사용, R1<-->R2는 RIP사용

- neighbor 수동 설정

conf t
router eigrp [AS]
neighbor [Neighbor IP] [Out Interface]

 

- R1 --> R2 Passiv interface설정

- 10.1.136.0/21 eigrp key chain 설정

- R2에서 1.1.128.0/22, 1.1.148.0/22 static routing 설정

- R2 EIGRP에서 static Redistribute (metric : 1544 2000 255 1 1500)

- Redistribute-list로 1.1.128.0/22 deny
