Hi Fernando,
adding to my own comment and to be more specific:
The existing RFCs are very clear in their wording that
the node identified in the Destination Address field of
the IPv6 header is free to do whatever it desires with
the packet it just received. After all, the packet was
addressed specifically to that node.
These nodes are called segment endpoint nodes in SRv6.
Only nodes that are *NOT* identified in the DA are
prohibited from making any changes.
This should be very clear, even if you seem to
wish that IPv6 had been defined differently.
Are you saying that IPv6 allows for in the network header insertion/removal?
If so, please tell me how AH, Path-MTU Discovery, and ICMPv6 error
reporting works -- all very basic functions of IPv6.
IPv6 is an end to end protocol. With RH you change the DA on the flight,
because routing only works based on the DA -- there's no other way to
specify waypoints.
If you claim otherwise, that can be, at best, a major misunderstanding
of how IPv6 works.
Thanks,
