The present invention provides a method and device for determining to establish a multi-protocol label switching traffic engineering tunnel. The method includes: receiving, by a first PE, an IGP notification message including information of a Mesh Group to which a second PE belongs and role information of the second PE released by the second PE, and then, determining, according to information of Mesh Groups to which the two belong, whether the two belong to a same Mesh Group; and after determining that the two belong to the same Mesh Group, determining, according to role information of the two, whether to establish the MPLS TE tunnel to the second PE. In the technical solutions of the present invention, the MpLS TE tunnel is established according to both information of a Mesh Group to which a PE belongs and role information of the PE, which avoids establishing an unnecessary MPLS TE tunnel, and overcomes a limitation in establishing the MPLS TE tunnel by using a Mesh Group solution. |
