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.
