Abstract: A method for obtaining link aggregation group (LAG) information, and a node and a system thereof are provided, which belong to the field of communication technologies. The method includes the following steps. An ingress node of a label switched path (LSP) sends an echo request message to another node on the LSP, in which the message carries identification information, and the identification information is for identifying that the LAG information on the LSP needs to be obtained. The ingress node receives an echo reply message returned by said another node, in which the message carries LAG information between said another node and a next hop node on the LSP. The present invention implements the obtaining of LAG information on the LSP and brings great convenience to OAM of MPLS network, and has the advantages of being simple, convenient, and easy to implement and having strong practicality.

The method includes: an ingress edge node sends a label request packet to a downstream node, where the label request packet carries an Equal Cost Multi-Path (ECMP) property flag of a Forwarding Equivalence Class (FEC); the downstream node that receives the label request packet sends the label request packet to a next-hop node according to the property flag; and the node that receives the label request packet performs label mapping according to a path of the label request packet, binds a label to the FEC, and sets up an LSP. An ECMP property flag indicating setting up an ECMP route is permitted is introduced in the process of setting up an LSP. Therefore, setup of an ECMP route is prevented for the FEC that imposes special requirements, and management and maintenance of the network are facilitated.
