Release Information

Statement introduced in Junos OS Release 9.2.

Statement introduced in Junos OS Release 12.2 for ACX Series routers.

Statement introduced in Junos OS Release 12.3 at the [edit protocols l2circuit local-switching interface interface-name] hierarchy level.

Description

Configure pseudowire redundancy for Layer 2 circuits and VPLS. A redundant pseudowire can act as a backup connection and can be configured between a PE router and a CE device or between PE routers, 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 customers.

Note: VPLS is not supported on ACX Series routers. The psn-tunnel-endpoint statement is not supported at the [edit protocols l2circuit local-switching interface interface-name end-interface interface interface-name] hierarchy level.

Options

address—Specifies the address for the backup neighbor.

The remaining statements are explained separately.

Required Privilege Level

routing—To view this statement in the configuration.

routing-control—To add this statement to the configuration.
