A method, a router and a software are provided for routing communication traffic along a path in a communication network, being an IGP shortcut. The method comprises: providing an IGP shortcut prefix to a routing entity and storing the IGP shortcut prefix in a Routing Information Base (RIB); associating a new flag with an LSP associated with the IGP shortcut prefix, wherein the new flag indicates whether that LSP can serve for conveying traffic when implementing MPLS connectivity; storing information that relates to the new flag at the RIB; identifying LSPs associated with respective IGP shortcut prefixes which qualify to operate as next hop routing paths' candidates, wherein the qualified LSPs are each associated with a flag indicating that the respective qualified LSP is MPLS reachable; selecting an LSP to be a next hop routing path, wherein the selection is made from among the qualified LSPs; and forwarding traffic towards its destination via the next hop LSP.

Method and a device for routing traffic along an IGP shortcut path

A system and a method are provided for use in an MPLS network, wherein the system comprises at least one routing element configured to share one or more circuits among multiple Intermediate System to Intermediate System (IS-IS) routing protocol instances, wherein each of the multi instances is associated with a unique database, and wherein the at least one routing element comprises a managing entity configured to: manage a plurality of traffic engineering software agents each associated with a respective database, and allocate available resources to respective instances; update at least one of the plurality of databases; and for traffic that is about to be conveyed via a specific instance, determine a neighboring instance through which said traffic will be conveyed, based on information comprised in the database associated with the specific instance through which said traffic will be conveyed.
