Configuring Node Protection or Link Protection for LSPs
When you configure node protection or link protection on a router, bypass LSPs are created to the next-hop or next-next-hop routers for the LSPs traversing the router. You must configure node protection or link protection for each LSP that you want protected. To extend protection along the entire path used by an LSP, you must configure protection on each router that the LSP traverses.
You can configure node protection or link protection for both static and dynamic LSPs.
To configure node protection on a router for a specified LSP, include the node-link-protection statement:
You can include this statement at the following hierarchy levels:
- [edit protocols mpls label-switched-path lsp-name]
- [edit logical-systems logical-system-name protocols mpls label-switched-path lsp-name]
To configure link protection on a router for a specified LSP, include the link-protection statement:
You can include this statement at the following hierarchy levels:
- [edit protocols mpls label-switched-path lsp-name]
- [edit logical-systems logical-system-name protocols mpls label-switched-path lsp-name]
 | Note: To complete the configuration of node or link protection, you must also configure link protection on all unidirectional RSVP interfaces that the LSPs traverse, as described in Configuring Link Protection on Interfaces Used by LSPs. |
