What It Means

This LSP event indicates that the destination route for the LSP is incorrect.

Cause

The IP address in the to statement at the [edit protocols mpls label-switched-path lsp-path-name] hierarchy level is incorrectly configured as the loopback (lo0) interface of this router itself, as indicated by the From address (10.0.0.1) which is identical to the empty route address (10.0.0.1).

Action

Enter the correct IP address for the egress router at the [edit protocols mpls label-switched-path lsp-path-name] hierarchy level.
