5.Router-Dynamic Routing(EIGRP)

EIGRP protocol

• administrative Distance : 90(D) 170(D, Dex)
• matrix : B,D,R,L,M
• code : D(같은 AS), D EX(재분배)
• Update : 순간 (빠르다)

EIGRP -wildcard mask

만약 같은 대역대지만 분리해서 보내고싶은곳과 보내고 싶지 않은 대역대가 있다면 와일드카드 마스크로 막아줄 수 있다. 1.1.12.0/24 대역대와 1.1.45.0/24 network [네트워크 주소] [ wildcard mask]
