我要問的東西有點奇怪,偏實務經驗,跟考試不太有關,純粹練功:
103年鐵特三級,網路。第二大題。
這題做完之後,我反問自己:
ICMP 不是應該都要很小的嗎?
為什麼這題竟然還要 IP Packet Fragmentation?
是出題的亂編數據嗎?
還是真有其事,若有可以舉得出實例嗎?
想了一下,我還真的想到實例:
ping 可以在 option 下 65535 bytes,雖然這是一個 Packet 最大值
不過其實我們是走 Ethernet 架構,MTU 只到 1500
所以這時底層就非 Fragmentation 不可
這是我自己想到的。
想問,ICMP 還有其它應用會需要 Fragmentation 的嗎?
