From 16e46548499d336899ee051e805ae4e5c92cc403 Mon Sep 17 00:00:00 2001 From: Andreas Herz Date: Fri, 21 Aug 2015 11:33:05 +0200 Subject: added missing icmpv6 codes in REJECT RFC 4443 added two new codes values for ICMPv6 type 1: 5 - Source address failed ingress/egress policy 6 - Reject route to destination And RFC 7084 states in L-14 that IPv6 Router MUST send ICMPv6 Destination Unreachable with code 5 for packets forwarded to it that use an address from a prefix that has been invalidated.
