请教大家一个问题:RFC 2460 中为什么说IPV6包头有些地方不能分割呢

h_virus

The Unfragmentable Part consists of the IPv6 header plus any
      extension headers that must be processed by nodes en route to the
      destination, that is, all headers up to and including the Routing
      header if present, else the Hop-by-Hop Options header if present,
      else no extension headers.

      The Fragmentable Part consists of the rest of the packet, that is,
      any extension headers that need be processed only by the final
      destination node(s), plus the upper-layer header and data.
我想知道，为什么IP包头不能分割呢，请兄台释疑
