EIGRP도 수동 서머리를 지원한다.
0.0.0.255 <- 와일드마스크
브로드캐스트주소 - 서브넷마스크값

- 255.255.255.0
-------------------------
0. 0. 0.255
router eigrp에서 서브넷 마스크를 쓸 일이 있을때 와일드마스크를 쓴다
network 172.16.1.0 classful 서브넷사용안함(기본서브넷)
network 172.16.12.0 0.0.0.255 classless 서브넷지원 -> no auto-summary 필요
EIGRP Metric <--목적지까지 가는 비용을 계산하는 방식 : RIP는 hop이었음

R4는 Rip 방식으로 통신하기 때문에, R4와 EIGRP가 통신하기 위해서는 R1에서 재분배를 해야한다.
