Configuring MAC Pinning on Trunk Interfaces in Virtual Switches 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 switches 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 trunk interfaces in virtual switch routing instance of a logical system.

To configure MAC pinning on trunk interfaces in virtual switches for logical systems:

  1. Configure the interface and specify the encapsulation.
  2. Create the logical system by specifying the name of the logical system and specify the trunk interface.
  3. Configure the routing instance as a virtual switch and specify the trunk interface.
  4. Configure the bridge domain and specify the list of VLAN IDs.
  5. Configure MAC pinning on the trunk interface at the [edit switch-options] hierarchy level.
  6. In configuration mode, verify the configuration.
