Configuring MAC Pinning on Access Interfaces 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 logical systems, you can configure MAC pinning. A set of logical systems within a single router can handle the functions previously handled by several small routers.

This topic describes how to configure MAC pinning on access interfaces of a logical system.

To configure MAC pinning on access interfaces in logical systems:

  1. Configure the access interface.
  2. Create the logical system by specifying the name of the logical system, and specify the access interface and list of VLAN IDs associated with the interface.
  3. Configure MAC pinning on the access interface by including the [mac-pinning] statement in the [edit bridge-domains] hierarchy.
  4. In configuration mode, verify the configuration.
