vtnet0|1 interface statistics

Junos telemetry interface (JTI) supports interface sensors for the vtnet0|1 interfaces. A vtnet0 interface communicates between Routing Engines and Packet Forwarding Engines. A vtnet1 interface communicates between the primary and secondary Routing Engines.
An MX Series router supports vtnet0|1 interface statistics in either of these scenarios:

• The router operates as the base system (BSYS).
• You assign line cards to the router, enabling it to operate as a guest network function (GNF).
