    abstract =  {In networks supporting IPv6 the Internet Control Message Protocol version 6 (ICMPv6) plays a fundamental role with a large number of functions, and a correspondingly large number of message types and options. A number of security risks are associated with uncontrolled forwarding of ICMPv6 messages. On the other hand, compared with IPv4 and the corresponding protocol ICMP, ICMPv6 is essential to the functioning of IPv6 rather than a useful auxiliary. This document provides some recommendations for ICMPv6 firewall filter configuration that will allow propagation of ICMPv6 messages that are needed to maintain the functioning of the network but drop messages which are potential security risks.},
