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.
[edit] 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. } } }
