Displaying General LSP Error Events

Sample Output

Meaning

The sample output from ingress router R1 is a section from the complete output. Typically, the output includes LSP events that led to an LSP failure and the 50 most recent state events. Only one example of a general LSP error event is displayed because it is impossible to provide all of the events described in this topic in one sequence of log history.

For completeness, events not generated by the example network used throughout this book are described to show LSP events that might occur in your network. The output for these events includes the prompt user@host rather than the usual user@R1 prompt.
