Abstract:
This proposal describes a mechanism that can be used to detect Data
Path Failures of various overlay technologies as VXLAN, NVGRE,
MPLSoGRE and MPLSoUDP and verifying/sanity of their Control and Data
Plane for given Overlay Segment. This document defines the following
for each of the above Overlay Technologies:
o Encapsulation of OAM Packet, such that it has same Outer and
Overlay Header as any End-System's data going over the same
Overlay Segment.
o The mechanism to trace the Underlay that is exercised by any
Overlay Segment.
o Procedure to verify presence of any given Tenant VM or End-System
within a given Overlay Segment at Overlay End-Point.
Even though the present proposal addresses Overlay OAM for VXLAN,
NVGRE, MPLSoGRE and MPLSoUDP, but the procedures described are
generic enough to accommodate OAM for any other Overlay Technology.
