relearn { permit | deny }
no relearn
Command introduced before JunosE Release 7.1.0.
Modifies the relearning subscriber policy for the subscriber (client) interfaces that belong
to a bridge group or to a VPLS instance. A bridge group or a VPLS instance learns the
addresses of network nodes by examining the MAC source address of every incoming
packet and creating an entry in the forwarding table that consists of the address and
associated interface where the packet was received. The relearn command defines
whether subscriber interfaces that belong to a bridge group or to a VPLS instance can
relearn a MAC address entry on a different interface from the one initially associated with
this entry in the forwarding table. The no version restores the default value, permit
relearning.
You cannot change the default subscriber policy values for trunk (server) interfaces that
belong to a bridge group or to a VPLS instance. You also cannot change the default
subscriber policy values for a VPLS virtual core interface, which acts as a trunk interface.
The VPLS virtual core interface represents all the MPLS tunnels from the router to the
remote VPLS edge (VE) devices.
permit—Enables the subscriber interfaces that belong to a bridge group or to a VPLS
instance to relearn a MAC address entry on a different interface from the one initially
associated with this entry in the forwarding table
deny—Prevents the subscriber interfaces that belong to a bridge group or to a VPLS
instance from relearning a MAC address entry on a different interface from the one
initially associated with this entry in the forwarding table; with this option, the interface
waits until the entry expires from the forwarding table to relearn it on the new interface
