Multiple routing instance support for ping overlay and traceroute overlay on VxLAN

Junos OS supports using ping overlay and traceroute overlay commands on a static VxLAN tunnel with multiple routing instances. The OAM packets created for the ping overlay and traceroute overlay commands follow the same underlay network path as the data packets. This allows you to verify the connectivity and to detect fault in the underlay network for an overlay segment between two VTEPs.
