remote-ip pwe3 (Remote MPLS LDP peer view)

Function

The remote-ip pwe3 command prevents an LSR from distributing labels to a specified remote peer for LDP services.

The undo remote-ip pwe3 command allows the device to assign labels for a specified remote peer for LDP services.

By default, allows the device to assign labels for a specified remote peer for LDP services.

Usage Guidelines

Usage Scenario

When a remote LDP session transmits LDP services, you can run one of the following commands to prevent an LSR from distributing labels to the remote peer to save system resources:

Run the remote-ip pwe3 command to prevent the LSR from distributing labels to a specified remote peer.
Run the remote-peer pwe3 command to prevent the LSR from distributing labels to all remote peers.
NOTE:
When a backbone network is deployed with TE services, that is, in the LDP over TE scenario, you cannot prevent an LSR from distributing labels to remote peers.
Specifically, after this function is configured, the device can still use LDP to distribute labels to L2VPN peers.

Prerequisites

Run the command mpls ldp remote-peer to configure remote LDP peer.

Example

# Prevent an LSR from distributing labels to the remote peer with the IP address and mask of 1.1.1.1/32.
