     Abstract 

        Ping is a widely deployed Operation, Administration, and Maintenance 
        (OAM) mechanism in networks.  This document describes a mechanism 
        for detecting data-plane failures using Ping in RFC7348 VXLAN based 
        EVPN networks.

     1. Introduction 

        RFC7348 Virtual eXtensible Local Area Network (VXLAN): A Framework 
        for Overlaying Virtualized Layer 2 Networks over Layer 3 Networks 
        defines means to support data center layer 2 E-VPN over an IP core 
        network. 

        draft-jain-bess-evpn-lsp-ping defines procedures to detect data-
        plane failures using LSP Ping in MPLS networks deploying EVPN and 
        PBB-EVPN, which is an extension of RFC6426. 

        This document outlines how OAM data fields are encapsulated and how
