6LoWPAN 在设计 IPv6 header 压缩主要是将 IPv6 headers 之间的共同值省略或是可以由 layer 2 header 取得数据而省略. 下列哪些叙述是正确的 ？A.version 欄位可省略, 因为都是 IPv6#B.Payload length 欄位可以省略, 因为可以由 Layer 2 header 计算得知#C.Source/Destination IPv6 address 欄位无法省略, 因为封包一定要有 IPv6 网址#D.如果是 Link-local IPv6 address 就可以省略, 因为 IPv6 网址的Interface ID 可以由 layer 2 MAC address 取得
