摘要：<p>Disclosed are a method and device for label lookup. The method for label lookup comprises: looking up, on the basis of a label in a packet, in a ternary content-addressable memory (TCAM) for a label attribute corresponding to the label, where the label comprises: an inner-layer label or an outer-layer label, and, the label attribute comprises: a forwarding label or a non-forwarding label; and, insofar that the label attribute is the forwarding label, looking up in a random access memory (RAM) on the basis of the forwarding label, and acquiring label forwarding information. The present invention achieves the effect of conserved network resources and increased packet forwarding rate.</p>
