The VPLS function between SPEs is similar to a common VPLS function.
By default, a network provider edge (NPE) does not forward the LDP MAC Withdraw messages received from other NPEs to UPEs, received from UPEs to other NPEs, or received from a UPE to other UPEs.
To speed up network convergence, enable the NPE to send an LDP MAC Withdraw message to accelerate MAC address updates on a VPLS network.
NPE refers to the network end peer of the local VSI in hierarchical virtual private LAN service (HVPLS). UPE refers to the user end peer of the local VSI in HVPLS.
In good network conditions, running this command speeds up network convergence. In bad network conditions, running this command generates a large number of exchange messages, and therefore is not recommended.

The L2VPN view is displayed.
MAC Withdraw loop detection is enabled.
After you configure MAC Withdraw loop detection on a provider edge (PE), the PE adds the Path type-length-value (TLV) field to a MAC Withdraw message before forwarding the message. If you do not configure MAC Withdraw loop detection on a PE but the PE receives a MAC Withdraw message, the PE directly forwards the message.
The configuration is committed.
