+ *
+ * In-band OAM (iOAM) is an implementation study to record operational
+ * information in the packet while the packet traverses a path between
+ * two points in the network.
+ *
+ * VPP can function as in-band OAM encapsulating, transit and
+ * decapsulating node. In this version of VPP in-band OAM data is
+ * transported as options in an IPv6 hop-by-hop extension header. Hence
+ * in-band OAM can be enabled for IPv6 traffic.
