A method for determining to establish a multi-protocol label switching traffic engineering tunnel. A first PE receives 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. Then, it determines, according to information of Mesh Groups to which the two belong, whether the two belong to a same Mesh Group. After determining that the two belong to the same Mesh Group, the first PE determines, according to role information of the two, whether to establish the MPLS TE tunnel to the second PE.
