RFC 2463 states that it is a MUST to limit the rate of ICMPv6 error messages that are sent. Traceroute is a utility that relies on ICMP error messages. One of the parameters for traceroute is the number of probes that are sent for each hopcount. RFC 2463 gives an example of 1 second as a conservative default if timer based rate limiting was implemented. If this is used, traceroute won't receive a reply for each probe if multiple probes are sent for each hopcount since some will be supressed due to the rate limiting factor. What are other implementations doing in regard to ICMPv6 rate limits?
