Abstract: Embodiments of this application disclose a tunnel establishment method. A first communication apparatus may receive first adjacency topology information sent by a second communication apparatus, and establish a first tunnel between the first communication apparatus and the second communication apparatus when the first adjacency topology information matches second adjacency topology information of the first communication apparatus. It can be learned that, in this solution, the first communication apparatus may locally store only the second adjacency topology information of the first communication apparatus. Compared with the conventional technology in which information about two endpoints of a tunnel needs to be configured on the first communication apparatus, configuration for the first communication apparatus is simpler.
