Release Information
Statement introduced in Junos OS Release 9.2.
Statement introduced in Junos OS Release 12.2 for the ACX Series Universal Access routers.
Description
Configures pseudowire redundancy for Layer 2 circuits and VPLS. A redundant pseudowire can act as a backup connection between a PE router and a CE device, maintaining Layer 2 circuit and VPLS services after certain types of failures. This feature can help improve the reliability of certain types of networks where a single point of failure could interrupt service for multiple customers.
 | Note: VPLS is not supported on ACX Series routers. |
Options
community—Specifies the community for the backup neighbor.
psn-tunnel-endpoint—Specifies the endpoint address for the packet switched network (PSN) tunnel on the remote PE router. The PSN tunnel endpoint address is the destination address for the LSP on the remote PE router.
standby—Configures 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 CE device. The CE device drops the traffic from the standby pseudowire, unless the active pseudowire fails. If the active pseudowire fails, the CE device automatically switches to the standby pseudowire.
virtual-circuit-id—Uniquely identifies the primary and standby Layer 2 circuits. This option is configurable for Layer 2 circuits only.
Required Privilege Level
routing—To view this statement in the configuration.
routing-control—To add this statement to the configuration.
