To record routes:
mpls te record-route

By default, both route
recording and label
recording are disabled.
Enabling loop detection
Enabling loop detection also enables the route recording feature, regardless of whether you have
configured the
mpls te record-route
command. Loop detection enables each node of the tunnel to
detect whether a loop has occurred according to the recorded route information.

Setting tunnel setup retry
If the ingress node fails to establish an MPLS TE tunnel, it waits for the retry interval, and then tries to
set up the tunnel again. It repeats this process until the tunnel is established or until the number of
attempts reaches the maximum. If the tunnel cannot be established when the number of attempts
reaches the maximum, the ingress waits for a longer period and then repeats the previous process.
