[보안] Static, Dynamic 연습 (feat.router 4개)

 

 

Static

 

Router(config)#ip route [목적지네트워크] [서브넷마스크] [보낼곳]

 

해당 네트워크 대역의 통신을 어느 인터페이스에 보낼지 등록

맨 뒤 값은 라우터의 ip로 변경 가능.

 

EX> Router(config)#ip route 192.168.10.0 255.255.255.0 fastEthernet 0/0

      

 

 

 

Dynamic

 

Router(config)#route rip

Router(config-router)#network 192.168.10.0

Router(config-router)#network 192.168.20.0

 

내가 알고있는 네트워크를 적어 네트워크 대역을 옆에 알려주는 것.

Static 실습

 

 

준비물 : router 4개, pc 2개

 

 

그리고 다음과 같이 주소를 할당해줄 예정입니다.

router 설정

 

첫번째 router ip

 

저의 Router1을 보면 Fa0/0, Fa0/1 순서대로 연결해줄 예정입니다.

0/0 --> 10.1이랑 연결

0/1 --> 20.1이랑 연결

 

 

Router(config)#int
Router(config)#interface f
Router(config)#interface fastEthernet 0/0
Router(config-if)#ip address 192.168.10.1 255.255.255.0

Router(config)#interface fastEthernet 0/1
Router(config-if)#ip address 192.168.20.1 255.255.255.0
Router(config-if)#no shut

Router(config-if)#
%LINK-5-CHANGED: Interface FastEthernet0/1, changed state to up

Router(config-if)#exit

 

do show run 명령으로 연결된 것 확인

 

 

 

 

 

첫번째 router static라우팅 설정

 

Router(config)#ip route 192.168.50.0 255.255.255.0 192.168.20.2

 

 

 

 

두번째 router ip 설정

 

 

저의 Router2를 보면 Fa0/0, Fa0/1 순서대로 연결해줄 예정입니다.

0/0 --> 20.2이랑 연결

0/1 --> 30.1이랑 연결
