> IPv6 provides a routing header option which allows a packet sender to
> indicate how the packet should be routed, overriding the routing knowledge
> present in a network.  This functionality is roughly equivalent to the
> "source routing" option in IPv4.  All nodes in an IPv6 network -- both
> routers and hosts -- are required by RFC 2640 to process such headers.
