The tunnel priority ranges from 0 to 7. The smaller the priority, the higher the priority.

IDP has something like the main network number. DSP has something like subnet number and host IP . Of course, the meaning of this IDP is relatively complicated.

Then discard until the data frame out of the MPLS domain, then the TTL in the IP header will start working. At the time of outbound, the TTL in the tag header is decremented by 1 and copied to the TTL in the IP header .
