[問題] 路由表問題請益
想請問以下有關路由表問題
目的地IP位址 網路遮罩 介面
64.20.44.0 /24 1
64.20.44.100 /30 2
64.20.32.0 /20 3
64.20.46.0 /23 4
64.0.0.0 /10 5
0.0.0.0 /0 6
若封包之目的地位址如下,路由器會使用哪個介面?
1. 64.20.44.102
2. 64.20.45.102
3. 64.20.47.102
4. 64.20.48.102
我自己答案是
1. 1 (64.20.44.X)
2. 2 or 3 (64.20.44.X~64.20.47.X or 64.20.32.X~64.20.47.X)
3. 5 (64.X.X.X)
4. 5 (64.X.X.X)
有高手可以幫忙看看是否正確嗎?
謝謝
