Menu Configuration in IOS for SP CCIE Lab

最近在看Workbook,真的覺得CCIE Lab走在時代潮流的尖端(因為大部份人都沒有使用這些技巧..),其中有一個很特別的題目,不但要考Menu的設定方式,同時也考到了考生對於這些指令的熟悉程度(每一個option都要執行一個command),個人覺得是一個很適合CCIE Lab的考題方向,設定本身不難但是如果沒有設定過就不容易在考試中靠DocumentCD找到solution,所以我在這邊把sample config列出來供各位參考。

假設ISP ABC要開放VPN帳號連線至PE Router的權限,提供XYZ Site進行遠端troubleshooting。為了方便控管並指導XYZ網管執行相關指令,ABC要在PE Router上設定一個Menu供VPN帳號登入之後會自然呼叫此Menu提供客戶使用。

此Menu提供功能如下:
  • Option 1 should display the IP routing table for VRF XYZ
  • Option 2 should display the BGP table for VRF XYZ
  • Option 3 should display the MPLS forward-table for VRF XYZ
  • Option 4 should display the BGP learned labels for VRF XYZ
  • Option 5 should display exit item out of the command line

設定完成之後,從遠端telnet利用VPN帳號登入PE Router,就會自動啟用Menu如下:
