METHOD AND ROUTING DEVICE FOR BFD SESSION ESTABLISHMENT

摘要

The embodiments of the application provide a method and routing device for BFD session establishment. On one hand, in the embodiments of the application, a first routing device sends a link identifier for identifying the bidirectional link to be detected and a first descriptor assigned by the first routing device for the bidirectional link to be detected to a second routing device, thereby enabling the second routing device to determine the bidirectional link to be detected according to the link identifier, and to create a first relationship of the bidirectional link to be detected, the first descriptor and a second descriptor, wherein the second descriptor is the descriptor assigned by the second routing device for the bidirectional link to be detected; the first routing device further receives a first BFD message sent by the second routing device through the bidirectional link to be detected according the first relationship, wherein the first BFD message comprises the first descriptor and the second descriptor, thereby enabling the first routing device to create a second relationship of the bidirectional link to be detected, the first descriptor and the second descriptor.
