Layer 2 pseudowire redundancy

More Information:

    Layer 2 pseudowire redundancy

    A redundant pseudowire acts as a backup connection between PE routers and CE devices, maintaining Layer 2 circuits and services after certain types of failures. Pseudowire redundancy improves the reliability of certain types of networks (metro, for example) where a single point of failure could interrupt service for multiple customers.
