[CISCO] EIGRP(Enhanced Interior Gateway Protocol)라우팅

EIGRP(Enhanced Interior Gateway Protocol)라우팅

• Rapid convergence를 지원한다.
• Rapid convergence를 위해 DUAL(Diffusing Update Algorithm)을 이용한다.
• Metric factor : Bandwidth, Delay를 이용한다.
- Reliability(신뢰도), Load(부하), MTU(Maxium Transmission Unit)
• CISCO 전용 이었으나 표준화 되었다. (IGRP는 단종)
• Routing info 전달에 BW가 최소화되어있다.
- Mulcast(224.0.0.10)를 이용한다.

2. 라우터 EIGRP 설정

R1(config)# router eigrp 100
R1(config‐router)# network 1.1.1.0
R1(config‐router)# network 12.1.1.0
R1(config‐router)# network 41.1.1.0

R2(config)# router eigrp 100
R2(config‐router)# network 12.1.1.0
R2(config‐router)# network 23.1.1.0

R3(config)# router eigrp 100
R3(config‐router)# network 3.3.3.0
R3(config‐router)# network 34.1.1.0
R3(config‐router)# network 23.1.1.0
 
R4(config)# router eigrp 100
R4(config‐router)# network 34.1.1.0
R4(config‐router)# network 41.1.1.0

패시브인터페이스 설정

R1(config)# router eigrp 100
R1(config‐router)# passive‐interface g0/0

# do show run​

3. 확인

R1# show ip protocols
R1# show ip eigrp topology
R1# show ip eigrp neighbor

---

4. DUAL

R1# show ip eigrp topology //변경전조회(feasible successor가없음)

R2# show int s0/0/0 //R2조회
R2(config)# int s0/0/0 
R2(config‐if)# delay 3000 //delay3000변경

R1# show ip eigrp topology //변경후확인

# show ip protocols

# show ip eigrp topology

완성
