Configuring MAC Pinning on VPLS CE Interface

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 VPLS customer edge (CE) trunk interface.

To configure MAC pinning on a VPLS CE interface:

  1. Configure the trunk interface and specify the list of VLAN IDs.
  2. Configure the VPLS routing instance and specify the CE interface.
  3. Configure MAC pinning on the VPLS CE interface.
  4. In configuration mode, verify the configuration.
