1. 서론

    오늘은 그동안 GNS로 공부했던 부분들을 실제 Router와 L3 Switch를 PC에 연결하여 설정하는 법을 배워보았다.

2. 본론

1. Cisco IOS

//Router
# int g0/1
# no sh
# ip add dhcp
!
# int g0/0
# no sh
!
# int g0/0.10
# encap dot 10
# ip add 192.168.10.254 255.255.255.0
!
# int g0/0.20
# encap dot 20
# ip add 192.168.20.254 255.255.255.0
!
# ip dhcp pool NET20
# network 192.168.20.0 255.255.255.0
# default-router 192.168.20.254
# dns-server 168.126.63.1
# lease 8
# class VLAN20
# address range 192.168.20.1 192.168.20.253
!
# int g0/0.20
# ip dhcp client class-id VLAN20
!
# access-list 10 permit 192.168.20.0 0.0.0.255
!
# ip nat inside source list 10 int g0/1 overload
!
# int g0/1
# ip nat outside
!
# int g0/0.10
# ip nat inside
!
# int g0/0.20
# ip nat inside

//Switch
# vlan 20
!
# int g1/0/1
# sw tr en do
# sw mo tr
!
# int g1/0/24
# sw ac vlan 20
# sw mo ac

3. 결론

    GNS를 통한 시뮬레이션과 실제 장비로 설정하는것에 별다른 차이는 없었다.
