Configuring MAC Pinning for All Pseudowires of the VPLS Site in a BGP-Based VPLS Routing Instance for Logical Systems

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 for all pseudowires of the VPLS site in a BGP-based VPLS routing instance for a logical system.

To configure MAC pinning for all pseudowires in a BGP-based VPLS Routing instance for a logical system:

  1. Configure the interface by specifying the encapsulation.
  2. Create the logical system and specify the trunk interface and list of VLAN IDs on the logical unit.
  3. Configure the VPLS routing instance and specify the trunk interface.
  4. Configure MAC pinning after specifying the routing protocol and the trunk interface.
  5. In configuration mode, verify the configuration.
