Ex.축약 & 재분배

Ex.Build Up

01.방법.

1. ip 주소 적기

2. network

3. DHCP Client, PAT 공인 주소

   R4)
    ip dhcp pool ciso 1
    network 223.255.255.0 255.255.255.0
    default-router 223.255.255.254
    ip dhcp excluded-address 223.255.255.254
   
    ip nat pool cisco 192.168.40.254 192.168.40.254 netmask 255.255.255.0
    access-list 10 permit 223.255.255.0 0.0.0.255
    ip nat inside source list 10 pool cisco overload
   
    interface e0/0
    ip nat inside
    interface s1/0
    ip nat outside
    interface s1/1
    ip nat outside
   

4. 축약
   

R1)
    interface s1/0
    ip summary-address rip 193.168.10.0 255.255.255.0

R5)
    interface s1/0
    ip summary-address eigrp 100 194.168.50.0 255.255.254.0

R7)
    router ospf 1
    area 70 range 196.168.70.0 255.255.254.0

R8)
    router ospf 1
    area 80 range 195.168.80.0 255.255.254.0

02. 결과

R1 축약 확인 완.

R4)

축약 확인 완.

R5)

03. 오류.

• ping 안 감 -> 재분배 안 함.
  
  
  

04. 오류 해결.

R5)
interface s1/0
ip summary-address eigrp 100 222.175.0.0 255.255.0.0

R8)
router ospf 1
summary0address 211.175.0.0 255.255.0.0

04. 결과.

05. 오류.

• 223.255.255.254는 eigrp 가 아님.
• DHCP Client에서는 밖으로 ping이 가야 됨. / 밖에서 회사 내부로는 ping이 되면 안 됨.
