MPLS LSP Link Protection and Node-Link Protection Terms and Acronyms
backup LSP
A redundant LSP used to reroute a single, primary LSP. Backup LSPs are found in link protection, node-link protection, and fast reroute redundancy methods.
bypass LSP
A logical trunk used to reroute multiple backup LSPs over a single connection protected with link protection.
link protection
A method of establishing bypass LSPs to provide rapid reroute capability for primary LSPs on a per-link basis. For more information about link protection, see the Junos MPLS Applications Configuration Guide.
node-link protection
A method of establishing bypass LSPs to provide rapid reroute capability for primary LSPs on a per-node basis. If node protection is unavailable, the LSP attempts to use link protection. For more information about node-link protection, see the Junos MPLS Applications Configuration Guide.
