On MX Series routers only, you can configure Layer 2 address learning and forwarding
properties in support of Layer 2 bridging. The router learns unicast media access control
(MAC) addresses to avoid flooding the packets to all the ports in a bridge domain. The
router creates a source MAC entry in its source and destination MAC tables for each MAC
address learned from packets received on ports that belong to the bridge domain.
To configure Layer 2 address learning in NSM:
In the NSM navigation tree, select Device Manager > Devices.
1.
Click the Device Tree tab, and then double-click the device to select it.
2.
Click the Configuration tab. In the configuration tree, expand Protocols > L2 Learning.
3.
