Configuring MAC Pinning on All Pseudowires of a Specific Neighbor of LDP-Based VPLS Routing Instance

A MAC move occurs when a MAC address frequently appears on a different physical interface than the one it was learned on. Frequent MAC moves indicate the presence of loops. To avoid loops across interfaces in virtual private LAN services (VPLS), you can configure MAC pinning.

This topic describes how to configure MAC pinning on all pseudowires of a specific neighbor of an LDP-based VPLS routing instance.

To configure MAC pinning on all pseudowires of a specific neighbor in a VPLS routing instance with LDP signaling:

  1. Configure the interfaces as trunk interfaces and specify the list of VLAN IDs.
  2. Configure the VPLS routing instance and specify the trunk interface.
  3. Configure the routing protocol and specify the trunk interface and the VPLS identifier.
  4. Configure MAC pinning after specifying the neighbor ID.
  5. In configuration mode, verify the configuration.
