Abstract
An enhanced, flooding-based routing protocol is described that provides label switched path session information. In one example, a transit router is intermediately positioned between at least two label edge routers. The transit router is configured to determine a maximum number of LSPs concurrently supported by the transit router and determine a number of LSPs concurrently established by the transit router and for which the transit router is responsible for switching packets to one or more of the two label edge routers. The transit router generates, in accordance with a link state routing protocol, a link state routing protocol message that specifies the LSP session information as the maximum number of LSP and the number of LSPs concurrently established. The transit router further transmits, to the label edge routers, the link state routing protocol message.
