Of course, if you are running in a single zone, you can use a full L1 router or a full L2 router solution. *Aug 18 11:31:44.598: !! activation level1 of MPLS TE ! Here there is a potential problem, because Level1 Router , do not know level2 routing (outside the region) information, instead of looking for the nearest L1 / L2 router to your destination, then it may appear sub-optimal path In order to solve this problem, IS-IS introduced a mechanism called route leakage. There are two types of tunnel priorities: Moreover, it is not necessary to maintain the matching time of both parties when establishing the adjacency relationship.

For example, the tunnel interface is manually shut down . Path: valid Link status changes The path calculation of the MPLS TE tunnel requires relevant information to be performed. Then we need to use a link state routing protocol to flood the link information to all routers running TE in the network . After collecting the information, the TE router establishes its own MPLS TE Database .
