Configuring MAC Pinning for All Pseudowires of the VPLS Routing Instance (LDP and BGP)

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 a trunk interface for all pseudowires of the VPLS routing instance.

To configure MAC pinning for the VPLS routing instance:

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