ICMPv6: Echo Reply Without Request
This protocol anomaly triggers when it detects an ICMPv6 echo reply without a matching echo request. This can indicate data tunneling over ICMPv6. Note: Seeing this alert can indicate that the detector is installed incorrectly, or that packets are being dropped or re-ordered somewhere.
