Layer 2 Learning and Forwarding in a Logical System Overview
You can partition a single physical router into multiple logical devices called logical systems that perform independent routing tasks. Logical systems perform a subset of the actions of a physical router and have their own unique routing tables, interfaces, policies, and routing instances. On MX Series routers only, you can enable Layer 2 learning and forwarding in a logical system for bridge domains or other virtual-switch routing instances.
When enabling Layer 2 learning and forwarding in a logical system for bridge domains or other virtual-switch routing instances, the following guidelines apply:
- You can only configure 16 logical systems.
- Logging is performed for the entire device and not per logical system.
- You cannot restart Layer 2 learning for an individual logical system.
