Release Information

Statement introduced in Junos OS Release 8.4.

Support for the switch-options statement added in Junos OS Release 9.2.

Support for top-level configuration for the virtual-switch type of routing instance added in Junos OS Release 9.2. In Junos OS Release 9.1 and earlier, the routing instances hierarchy supported this statement only for a VPLS instance or bridge domain configured within a virtual switch.

Support for logical systems added in Junos OS Release 9.6.

Description

(MX Series routers only) Disable MAC learning for a virtual switch, for a bridge domain, for a specific logical interface in a bridge domain, or for a set of bridge domains associated with a Layer 2 trunk port.

Note: When MAC learning is disabled for a VPLS routing instance, traffic is not load balanced and only one of the equal-cost next hops is used.

Default

MAC learning is enabled. Use no-mac-learning to disable MAC learning.

Required Privilege Level

routing—To view this statement in the configuration.

routing-control—To add this statement to the configuration.
