Abstract: The filter is provided, which includes a filter body and resonant cavities disposed on the filter body, and further includes an input port and an output port that are disposed on the filter body. At least one of the input port or the output port is connected to a set of additional resonant cavities, and each set of additional resonant cavities includes: a first additional resonant cavity in signal coupling to the input port or the output port, and a second additional resonant cavity in signal coupling to the first additional resonant cavity. In the filter, the two additional resonant cavities and another resonant cavity connected to the input port or the output port are in a form of a straight line, thereby implementing a flexible layout of cavities of the filter. In addition, a coupling structure is simple, costs are low, reliability and batch consistency is good.

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.
