The Nokia perimeter router must be configured to drop IPv6 packets containing the network service access point (NSAP) address option within the Destination Option header.

Description
The optional and extensible natures of the IPv6 extension headers require higher scrutiny since many implementations do not always drop packets with headers they cannot recognize, and hence could cause a denial of service on the target device. In addition, the type, length, value (TLV) formatting enables headers to be very large. This option type from RFC 1888 (Open Systems Interconnection [OSI] NSAPs and IPv6) has been deprecated by RFC 4048.

This requirement is not applicable for the DODIN Backbone. Review the router configuration and determine if filters are bound to the applicable interfaces to drop IPv6 packets containing a Destination Option header with option type value of 0xC3 (NSAP address). Verify the IPv6 filter has the Next Header value set to "60", as shown in the example below: - show filter ipv6 40 Entry : 10 Description : (Not Specified) Log Id : n/a Src. IP : ::/0 Src. Port : n/a Dest. IP : ::/0 Dest. Port : n/a Next Header : 60 Verify an "Ing IPv6 Flt" has been applied to the interface, as shown in the example below: - show router interface "TO-PE2" detail | match "Ingr IPv6 Flt" Egr IPv6 Flt : none Ingr IPv6 Flt : 40 If the router is not configured to drop IPv6 packets containing the NSAP address option within the Destination Option header, this is a finding.

Fix Text (F-88317r1203789_fix)

Configure the router to drop IPv6 packets containing a Destination Option header with the option type value of 0xC3 (NSAP address). Configure an IPv6 filter: - config>filter# ipv6-filter 40 create - config>filter>ipv6-filter# entry 10 create - config>filter>ipv6-filter>entry# match next-header 60 - config>filter>ipv6-filter>entry>match# back - config>filter>ipv6-filter>entry# action drop - config>filter>ipv6-filter>entry# exit all Apply the IPv6 filter to the interface: - configure router interface "TO-PE2" ingress filter ipv6 40
