Usage Guidelines

Usage Scenario

On enterprise networks, you need to run the npe-upe mac-withdraw enable command to enable an SPE to forward the LDP MAC Withdraw messages received from other SPEs to UPEs.

Prerequisites

LDP has been configured as the PW signaling protocol using the pwsignal ldp command.

Precautions

The npe-upe mac-withdraw enable command is used on SPEs.

An SPE refers to the network end peer of the local VSI in HVPLS. You can run the peer peer-address [ negotiation-vc-id vc-id ] [ tnl-policy policy-name ] command to specify an SPE.
A UPE refers to the user end peer of the local VSI in HVPLS. You can run the peer peer-address [ negotiation-vc-id vc-id ] [ tnl-policy policy-name ] upe command to specify a UPE.
If the local device is not configured with HVPLS, the npe-upe mac-withdraw enable command is not required.

Example

# Enable the SPE to forward the LDP MAC Withdraw messages received from other SPEs the UPE.
