show interfaces (Multicast Tunnel)
Syntax
show interfaces interface-type <brief | detail | extensive | terse> <descriptions> <media> <snmp-index snmp-index> <statistics>
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.
