Detailed Description

In-band OAM (iOAM).

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.
