Suppose A below router E , E made to be a packet to D under F. , The data packet is A tag the transferred B , assumed that the BC loop appears between subsequent label TTL is decremented to 0 , since the TTL value The setting is very small, so very quickly, the TTL is decremented to 0. At this time, B (message discarder) will send an ICMP error message back to E. Then, if B has E route (or label), B will The ICMP error message will be sent directly back to E. If not, B will continue to tag the error message and gradually pass it to D , D.As the PE , about E route, then back to the label and then loaded on E . Then, no matter what the situation, the final E can receive the ICMP error message generated by B.
