The invention discloses a method and a device for building a tunnel. The method includes: detecting the local tunnel interface is configured on the required bandwidth and destination identifier; try to establish TE traffic engineering tunnel from the local bandwidth required to meet the destination; if so, determine whether established successfully, the end of the process; otherwise, in all links from the local to the destination, select the link group meet the following conditions: all links of the link group in the remaining bandwidth and not less than the required bandwidth, a small TE tunnel were established for each link of the link bandwidth utilization group; all TE binding tunnel will be established in the link group on a TE tunnel. The invention utilizes the bandwidth resource in the network more rationally.
