IPv6 Inspection

•Information about IPv6 Inspection, page 11-48

Information about IPv6 Inspection

IPv6 inspection lets you selectively log or drop IPv6 traffic based on the extension header. In addition, IPv6 inspection can check conformance to RFC 2460 for type and order of extension headers in IPv6 packets.

Default Settings for IPv6 Inspection

If you enable IPv6 inspection and do not specify an inspection policy map, then the default IPv6 inspection policy map is used, and the following actions are taken:

•Allows only known IPv6 extension headers

•Enforces the order of IPv6 extension headers as defined in the RFC 2460 specification

If you create an inspection policy map, the above actions are taken by default unless you explicitly disable them.

(Optional) Configuring an IPv6 Inspection Policy Map

To identify extension headers to drop or log, and/or to disable packet verification, create an IPv6 inspection policy map to be used by the service policy.

Detailed Steps

Step 1 Choose Configuration > Firewall > Objects > Inspect Maps > IPv6. The Configure IPv6 Maps pane appears.
