JUNOSe 9.1.x Command Reference Guide A to M > B Commands > bridge learn

bridge learn

Description: 

Sets the maximum number of dynamic MAC addresses that a bridge group or VPLS instance can learn. The no version restores the default value, 0 (zero) learned addresses. The default value implies that there is no maximum number of learned entries for an individual bridge group or VPLS instance; that is, a bridge group or VPLS instance can learn an unlimited number of MAC addresses, up to the maximum number that the router supports.

To enable or disable the ability of a bridge group or VPLS instance to learn dynamic MAC addresses, use the bridge acquire command.

NOTE: For information about the maximum number of learned MAC address entries combined for all bridge groups and VPLS instances supported per chassis, see JUNOSe Release Notes, Appendix A, System Maximums.

Syntax: 

bridge { bridgeGroupName | vplsName } learn addressCount
