More Information
Summary:The present invention relates to methods and arrangements in an MPLS-TP network, comprising a plurality of interconnected routers configured for MPLS-TP, wherein at least a first router is defined as an originating Maintenance End Point, MEP, a second router is defined as a targeting MEP and the third router is defined as a Maintenance Intermediate Point, MIP. The basic idea of the present invention is to associate a table with each MIP and MEP, wherein the tables comprises information related to the MEPs of the MPLS-TP network and the information from the tables is inserted in the reply packets and forwarded packets. By using this information, the OAM packets can find the subsequent MIP or MEP and failure localization may be performed.
