This document describes a non-standard, but widely implemented,
modification to TCP's handling of ICMP soft error messages that
rejects pending connection-requests when those error messages are
received.  This behavior reduces the likelihood of long delays
between connection-establishment attempts that may arise in a number
of scenarios, including one in which dual-stack nodes that have IPv6
enabled by default are deployed in IPv4 or mixed IPv4 and IPv6
environments.  This memo provides information for the Internet community.

This document is a product of the TCP Maintenance and Minor Extensions Working Group of the IETF.
