Multiprotocol Label Switching (MPLS) label-switched path (LSP) link protection and node-link protection are facility-based methods used to reduce the amount of time needed to reroute LSP traffic. These protection methods are often compared to fast reroute—the other JUNOS software LSP protection method.
While fast reroute can only protect LSPs on a one-to-one basis, link protection and node-link protection can protect multiple LSPs by using only a single, logical bypass LSP. Link protection can provide robust backup support for a link, node-link protection can bypass a node or a link, and both types of protection are designed to interoperate with other vendor equipment. Such functionality makes link protection and node-link protection excellent choices for scalability, redundancy, and performance in MPLS-enabled networks.
