standby (Protocols Layer 2 Circuit)


Hierarchy Level


Configure the pseudowire to the specified backup neighbor as the standby. When you configure this statement, traffic flows over both the active and standby pseudowires to the backup device (either a CE device or PE router). The backup device drops the traffic from the standby pseudowire, unless the active pseudowire fails. If the active pseudowire fails, the backup device automatically switches to the standby pseudowire.

The standby statement is quite similar to the hot-standby statement introduced in Junos OS Release 12.3. The hot-standby statement allows for a faster forwarding-path switchover during transition periods, as compared to what is allowed by the standby statement.
