This string is the operator-assigned name of a transit LSP that was set up dynamically via RSVP-TE signaling rather than typed in manually hop by hop. Because dynamic transit tunnels can be created and torn down automatically as paths reroute, this name is what lets an admin match a row in this table back to the tunnel they see referenced in syslog or in a head-end router's configuration. For example, a name like backbone-lsp-nyc-chi-03 tells the admin at a glance which core path segment this transit row belongs to without cross-referencing tunnel indexes.
