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.
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.
