Each extension header has its own Next Header field as its first octet, with the same meaning as (but different relative location from) the corresponding field of the fixed IPv6 header. You can use these together with the extension headers' length fields to step through the extension headers until you find the transport layer header. WebI imagine this kind of protocol stubbing was its original intended purpose. If the Payload Length field of the IPv6 header indicates the presence of octets past the end of a header whose Next Header field contains 59, those octets must be ignored, and passed on unchanged if the packet is forwarded.
