R3303-HP HSR6800 Routers MPLS Command Reference

150
When using the undo mpls te ds-te ietf te-class command, make sure that the CT and preemption priority
of the TE class mapping to be restored to are not those of an existing TE class mapping.
After a TE class is modified, the device will notify the IGP to re-advertise the bandwidth information for
all TE interfaces, and will remove and then re-establish the CR-LSPs of the TE class on all TE interfaces.

# Associate TE class 7, CT 2, and preemption priority 3 in the IETF mode.
