摘要
A method for allocating a global label is provided, including: receiving, by a controller, a first message sent by a forwarding apparatus, where the first message carries a first label range, multiple labels included in the first label range are a subset of multiple labels included in a label space of the forwarding apparatus, and the first label range is not equal to the label space of the forwarding apparatus; and allocating, by the controller, a global label to the forwarding apparatus according to the first label range carried in the first message, where the global label is a label in the first label range. In addition, a method for obtaining a global label, a controller, and a forwarding apparatus are further provided. The foregoing solutions improve efficiency of global label allocation.
