me mip te bidirectional-lsp

Function

The me mip te bidirectional-lsp command creates a maintenance entity (ME) instance on a maintenance entity group intermediate point (MIP) and binds the ME instance to a transit node over a static bidirectional co-routed label switched path (LSP).

The undo me mip te bidirectional-lsp command deletes an ME instance created on a MIP.

By default, no ME instance is created.

Format

me mip te bidirectional-lsp lsp-name-str_cx [ mip-id mip-id-value ]

undo me mip te bidirectional-lsp lsp-name-str_cx

Parameters

Usage Guidelines

Usage Scenario

Two P2P label switched paths (LSPs) in opposite directions are established over a bidirectional co-routed transport path in a MEG. This means that there is a single LSP in both directions between a MEP and its RMEP. A single ME operates along this P2P LSP. On an LSP, a maintenance entity group end point (MEP) is configured on the ingress and a remote MEP (RMEP) is configured on the egress. A MIP is configured on the transit node.

To monitor the path between the MEP and the MIP using MPLS-TP OAM, create ME instances on both the MEP and MIP. To create an ME instance on the MIP and bind it to a specified LSP, run the me mip te command.

MPLS-TP OAM supports only the loopback (LB) function to monitor a path from a MEP to a MIP. If a MEP sends a loopback message (LBM), a destination node MIP can be specified. After receiving the LBM, the MIP responds to the MEP with a loopback reply (LBR). This process completes the LB operation.

Prerequisites

A transit node exists on a static bidirectional co-routed LSP.

Configuration Impact

After the me mip te bidirectional-lsp command is run:

The MIP responds to the MEP with LBRs and does not initiate the LB detection.
The MIP does not support performance statistics.
The MIP does not detect the MEG ID on the MEP side and cannot verify the MEG ID.

Example

# Create an ME instance on the MIP.
