Link path discovery

摘要

A method includes identifying, by a first router, a number of label switched paths from the first router to a destination router, wherein each of the label switched paths includes less than a predetermined number of routers. The method may also include storing, for each of the label switched paths, information identifying each router in the label switched path. The method may further include identifying a least cost label switched path based on the stored information.

1. A method, comprising:
identifying, by a first router, a plurality of label switched paths from the first router to a destination router, wherein each of the label switched paths includes less than a predetermined number of routers and each of the routers routes data via multiprotocol label switching, wherein the predetermined number of routers is set by a user, and wherein the identifying a first one of the plurality of label switched paths comprises:
accessing a first database stored in the first router; storing, for each of the plurality of label switched paths, information identifying each router in the label switched path; outputting, for display, information identifying each of the plurality of label switched paths; and identifying a least cost one of the plurality of label switched paths based on the stored information, wherein the accessing the first database comprises:
identifying a plurality of advertising routers capable of accessing the destination router.
