使用Cisco L3 Switch做VLAN的Routing

目標: 讓VLAN100與VLAN200的電腦透過L3 Swtich做VLAN的Routing，並且可以互相存取資源與上網，另外再使用Windows Server 2012配發VLAN100,VLAN200的IP Firewall: 使用ASUS AP當Firewall，並設兩條Static Route Switch: Core Switch為Cisco 3750切VLAN 10,VLAN100,VLAN200，VLAN10為預設的VLAN，VLAN100為Sales，VLAN200為RD Edge Switch為Cisco 3750與2950，其中2950為VLAN100，3750為VLAN200，如果要By Port切VLAN也可以，這裡只是為了方便說明，所以Edge Switch都直接設為單一VLAN Core Switch的設定 原本我只想Show Running-config其中比較重要的設定，後來想想還是全部列出，用紅色標記重要的設定 Gi 1/0/1接2950 Gi 1/0/2接3750 Gi 1/0/24接Router Core-3750#show running-config Building configuration...
