 This section provides the users with gap analysis regarding IPv6 feature requirements with
-OpenStack Ocata Official Release and Open Daylight Carbon Official Release. The gap analysis
+OpenStack Pike Official Release and Open Daylight Nitrogen Official Release. The gap analysis
 serves as feature specific user guides and references when as a user you may leverage the
 IPv6 feature in the platform and need to perform some IPv6 related operations.

-IPv6 Gap Analysis with Open Daylight Carbon
-===========================================
-
-This section provides users with IPv6 gap analysis regarding feature requirement with
-Open Daylight Carbon Official Release. The following table lists the use cases / feature
-requirements of VIM-agnostic IPv6 functionality, including infrastructure layer and VNF
-(VM) layer, and its gap analysis with Open Daylight Carbon Official Release.
-
-**Open Daylight Carbon Status**
-
-In Open Daylight Carbon official release, the legacy ``Old Netvirt`` identified by feature
-``odl-ovsdb-openstack`` is deprecated and no longer supported. The ``New Netvirt``
-identified by feature ``odl-netvirt-openstack`` is used.

+(VM) layer, and its gap analysis with Open Daylight Nitrogen Official Release.
+
+**Open Daylight Nitrogen Status**
+
+In Open Daylight Nitrogen official release, the legacy ``Old Netvirt`` identified by feature
+``odl-ovsdb-openstack`` is deprecated and no longer supported. The ``New Netvirt``
+identified by feature ``odl-netvirt-openstack`` is used.
