Understanding GMPLS Events

This chapter describes Generalized Multiprotocol Label Switching (GMPLS) error events that might occur in the output of the show mpls lsp extensive command. Descriptions typically include sample output of the label-switched path (LSP) event, an explanation of what the event means, the possible cause of the event, and any possible actions that you can take. (See Table 10.)
