CCNA3 Lab 1-3-1: 練習網段分割及基本設定

本次練習是參考Cisco網路學院
CCNA Exploration 4.0 LAN Switching and Wireless
Student Lab Manual
我將它轉成Dynamips的設定檔 並寫下自己的實驗紀錄

Dynamips的設定檔:

這Lab只是練習網段分割及基本設定
假設取得了一個192.168.7.0/24
要分割給Subnet A & B
Subnet A 需要有110台電腦
Subnet B 需要有54台電腦
該如何做

我的設定是
Subnet A: 192.168.7.0/25
Subnet B: 192.168.7.128/26

RouterA設定檔:
hostname Router1
!
no ip domain lookup
!
interface Loopback0
 description SubnetA_R1F0/0_Host1
 ip address 192.168.7.1 255.255.255.128 secondary
 ip address 192.168.7.126 255.255.255.128
!
interface FastEthernet0/1
 no switchport
 ip address 192.168.7.190 255.255.255.192
 no shutdown
!
line con 0
 logging synchronous
!
end

Switch1設定檔:
hostname Switch1
!
no ip routing
!
no ip domain lookup
!
line con 0
 logging synchronous
!
end

Host2設定檔:
hostname Host2
no ip domain lookup
!
interface FastEthernet0/2
 no switchport
 ip address 192.168.7.129 255.255.255.192
 no shutdown
!
ip route 0.0.0.0 0.0.0.0 192.168.7.190
!
line con 0
 logging synchronous
!
end

最後互ping 有通 結束
