From draft-gont-opsec-ipv6-eh-filtering-00.txt:
2.3.1.5. Advice
Intermediate systems should, by default, drop packets containing a
IPv6 Hop-by-Hop Option Extension Header.
The currently required behavior of HBH option type "00" in RFC2460:
4.2 Options
Two of the currently-defined extension headers -- the Hop-by-Hop
Options header and the Destination Options header -- carry a variable
number of type-length-value (TLV) encoded "options", of the following
format:
...
The Option Type identifiers are internally encoded such that their
highest-order two bits specify the action that must be taken if the
processing IPv6 node does not recognize the Option Type:
00 - skip over this option and continue processing the header.
