Data Preparation
To complete the configuration, you need the following data.

IS-IS Auto FRR should be configured so that service traffic between P nodes can be rapidly
switched to the TE tunnel when the direct link fails.
Traffic between P nodes should be transmitted only between the P nodes at the core layer
to prevent traffic between P nodes from going back to PE nodes.
NOTE
In this configuration example, PE1 and PE3 are used for illustration, only three P nodes of each plane at
the core layer are illustrated, and only the MPLS TE tunnel between P1 and P3 is illustrated. In real-world
situations, there are far more PE nodes, P nodes, and MPLS TE tunnels.
Assign IP addresses to interfaces on each node, configure the loopback addresses that are
used as LSR IDs, and configure IS-IS to implement IP connectivity.
Configure an MPLS TE tunnel between P nodes as the backup path in Loop-Free Alternate
(LFA) calculation.
Enable forwarding adjacency and configure LDP over TE.
Enable IS-IS Auto FRR so that traffic can be rapidly switched in the case of a link fault.
Run the undo isis lfa-backup command on the interfaces that connect P nodes to PE nodes
to disable these interfaces from becoming the backup interfaces in LFA calculation and
prevent traffic between P nodes from going back to PE nodes.
