Defining Label-Switched Paths for the FA-LSP
Next, define your FA-LSP by including the label-switched-path statement at the [edit protocols mpls] hierarchy level. Include the router ID of the peer in the to statement at the [edit protocols mpls label-switched-path] hierarchy level. Because packet LSPs are unidirectional, you must create one FA-LSP to reach the peer and a second FA-LSP to return from the peer.

protocols {
mpls {
label-switched-path lsp-name {
from ip-address;
to ip-address;
primary path-name;
secondary path-name;
no-cspf; # This statement to disable CSPF is optional.
}
}
