<p>The present invention discloses a method, an apparatus, and a system for distributing labels in a seamless multi-protocol label switching network, said invention relating to the multi-protocol label switching technical field, decreasing the complexity of an access node device greatly, reducing the operation cost of an operator effectively, and improving the scalability of the system. The method for distributing labels in a seamless multi-protocol label switching network provided by embodiments of the present invention includes: obtaining the label information of a first access node, wherein said label information includes the pseudo wire (PW) destination address of the first access node; sending said label information to a second router by utilizing a Border Gateway Protocol (BGP) message or a Target-Label Distribution Protocol (T-LDP) message, so that said second router can configure the PW label and/or flow label of the first access node to a second access node according to said label information and by using the access network configuration protocol. The present invention is applicable to scenarios in which labels are needed to be distributed.</p> |
