Fix Recommendation

Configure the router to drop IPv6 packets containing a Destination Option header with option type values of 0x05 (Router Alert) or 0xC2 (Jumbo Payload).

Configure an IPv6 filter to drop packets with a next-header value of 60 (value 60 corresponds to the Destination Option header). This will drop all packets with a Destination Option header.

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

Check Contents

This requirement is not applicable for the DODIN Backbone.

Review the router configuration and determine if filters are bound to the external interfaces to drop IPv6 packets containing a Destination Option header with option type values of 0x05 (Router Alert) or 0xC2 (Jumbo Payload).

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 a Destination Option header with invalid option type values, this is a finding.
