Configuring GMPLS Bidirectional LSPs

Because MPLS and GMPLS use the same configuration hierarchy for LSPs, it is helpful to know which LSP attributes control LSP functionality. Standard MPLS packet-switched LSPs are unidirectional, whereas GMPLS nonpacket LSPs are bidirectional.

If you use the default packet-switching type of psc-1, your LSP becomes unidirectional. To enable a GMPLS bidirectional LSP, you must select a non-packet-switching type option, such as lambda, fiber, or ethernet. Include the switching-type statement at the [edit protocols mpls label-switched-path lsp-name lsp-attributes] hierarchy level:



[edit protocols mpls label-switched-path lsp-name lsp-attributes]

switching-type (lambda | fiber | ethernet);
