Configuring Learning Domains for VLAN IDs Bound to Logical Interfaces

A learning domain is a MAC address database to which the MAC addresses are added based on the normalized VLAN tags. The normalized VLAN tags associated with a learning domain are always carried within packets sent over VPLS virtual interfaces.

To configure bridging for several VLANs using a minimal amount of configuration and switch resources, use the vlan-id all configuration statement to implicitly configure multiple learning domains for a bridge domain or VPLS instance:

  • For a logical interface with a single VLAN tag, the statement implicitly creates a learning domain for each normalized VLAN of the interface.
  • For a logical interface with dual VLAN tags, the statement implicitly creates a learning domain for each inner VLAN (normalized VLAN).
