Description

Display status information about the specified multicast tunnel interface and its logical encapsulation and de-encapsulation interfaces.

Options

`interface-type`	On M Series and T Series routers, the interface type is mt-`fpc`/`pic`/`port`.
brief \| detail \| extensive \| terse	(Optional) Display the specified level of output.
descriptions	(Optional) Display interface description strings.
media	(Optional) Display media-specific information about network interfaces.
snmp-index `snmp-index`	(Optional) Display information for the specified SNMP index of the interface.
statistics	(Optional) Display static interface statistics.

Additional Information

The multicast tunnel interface has two logical interfaces: encapsulation and de-encapsulation. These interfaces are automatically created by the Junos OS for every multicast-enabled VPN routing and forwarding (VRF) instance. The encapsulation interface carries multicast traffic traveling from the edge interface to the core interface. The de-encapsulation interface carries traffic coming from the core interface to the edge interface.
