You can run LDP over LSPs established by RSVP, effectively tunneling the LDP-established LSP through the one established by RSVP. To do so, enable LDP on the lo0.0 interface (see Enabling and Disabling LDP). You must also configure the LSPs over which you want LDP to operate by including the ldp-tunneling statement at the [edit protocols mpls label-switched-path lsp-name] hierarchy level:
- [edit]
- protocols {
-
-
mpls {
-
-
label-switched-path lsp-name {
-
from source;
-
to destination;
-
ldp-tunneling;
- }
- }
- }
For a list of hierarchy levels at which you can include this statement, see the statement summary section for this statement.
