But, if they recognize it, it is not *unknown* anymore. Seems > to be a "thought loop". The 8-bit "next header" field, the first byte, uses the same coding as the IPv4 Protocol field. And the next 8 bits after that provide the length of the EH. Why can't the intermediate node work its way down all unknown EHs until it reaches a "next header" you can identify? This should always occur.
