relearn
Syntax
relearn { permit | deny }
no relearn
Release Information
Command introduced before JUNOSe Release 7.1.0.
Description
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.
Options
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
