Command introduced before JUNOS Release 7.4.
Display status information about the specified multicast tunnel interface and its logical encapsulation and de-encapsulation interfaces.
interface-type — On M-series and T-series routing platforms, the interface type is mt-fpc/pic/port. On the J-series routing platform, the interface type is mt-pim/0/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.
The multicast tunnel interface has two logical interfaces: encapsulation and de-encapsulation. These interfaces are automatically created by the JUNOS software 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.
