Establishing FA-LSP Path Information
When you configure explicit LSP paths for an FA-LSP, you must use the traffic engineering link remote address as your next-hop address. When CSPF is supported, you can use any path option you wish. However, when CSPF is disabled with the no-cspf statement at the [edit protocols mpls label-switched-path lsp-name] hierarchy level, you must use strict paths.
[edit] protocols {mpls {path path-name { next-hop-address (strict | loose); }}}
 | Note: If the end-to-end LSP originates on the same routing platform as the FA-LSP, you must disable CSPF and use strict paths. |
