Configuring MAC Pinning on VPLS CE Interface 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 on a VPLS customer edge (CE) trunk interface in a logical system.

To configure MAC pinning for VPLS customer edge interface for logical systems:

  1. Configure the interfaces by specifying the encapsulation.
  2. Create the logical system by specifying the name and the trunk interface on the logical unit.
  3. Configure the VPLS CE interface and VPLS routing instance.
  4. Configure MAC pinning on the VPLS CE interface.
  5. In configuration mode, verify the configuration.
