IS-IS should be configured to implement IP connectivity between nodes.
Traffic between P nodes at the core layer should be transmitted through the direct link when
no link fault occurs.
The MPLS TE tunnel should be configured as the backup path so that traffic between P
nodes can be switched to the other plane when the link between P nodes fails.
