show interfaces routing 
<brief | summary | detail> 
<interface-name> 
<logical-system (all | logical-system-name)>

Description

Display the state of the router's interfaces. Use this command for performing router diagnostics only, when you are determining whether the routing protocols and the Junos OS differ about the state of an interface.

Options

none	Display standard information about the state of all router interfaces on all logical systems.
brief \| summary \| detail	(Optional) Display the specified level of output.
`interface-name`	(Optional) Name of a specific interface.
logical-system (all \| `logical-system-name`)	(Optional) Perform this operation on all logical systems or on a particular logical system.
