It is amusing for you to say that. As a co-author of the ICMPv6 RFC
2463, and RFC 1885, work which started in 1994, I have a good insight on
the
Multiplying the ICMP rate a node originates by the number of
interfaces should not make much of a difference
operationally, and if
a router has many interfaces it also has more paths to spread this
traffic over. On the other hand, for a strictly software based
router, having to

If that is the case, Pekka is not alone. I also get the
perception that it is talking about generating the ICMPv6

If the router can know that they are error messages and can also know,
e.g., that the errors are arriving at a disproportionally
high rate with
respect to the IPv6 packets that could have possibly generated them,
then it should perform rate limiting.

I will not respond to your other message as you seem to have a
fundamental misunderstanding of the context of the word send in the
rate-limiter specification, so any discussion about that would be
useless.
