Usage Guidelines

Usage Scenario

After configuring MPLS OAM for a static bidirectional co-routed LSP, run the display mpls oam bidirectional-tunnel command to view MPLS OAM information.

To view MPLS OAM information of all tunnels, run the display mpls oam bidirectional-tunnel all command.
To view MPLS OAM information of a specified tunnel, run the display mpls oam bidirectional-tunnel tunnel tunnelType tunnelNum command.

Prerequisites

MPLS OAM has been configured for a static bidirectional co-routed LSP.

Example

The actual command output varies according to the device. The command output here is only an example.
