The RUCKUS ICX perimeter router must be configured to drop IPv6 undetermined transport packets.

Overview

Finding ID	Version	Rule ID	IA Controls	Severity
V-273650	RCKS-RTR-000830	SV-273650r1110949_rule	CCI-002403	medium
Description
One of the fragmentation weaknesses known in IPv6 is the undetermined transport packet. This packet contains an undetermined protocol due to fragmentation. Depending on the length of the IPv6 extension header chain, the initial fragment may not contain the layer four port information of the packet.

Check Text (C-273650r1110949_chk)

This requirement is not applicable for the DODIN Backbone. Review configuration for the command below: ipv6 deny-undetermined-transport any any If the router is not configured to drop IPv6 undetermined transport packets, this is a finding.

Fix Text (F-77646r1109971_fix)

Add the command below to the global configuration: ICX(config)#ipv6 deny-undetermined-transport any any
