The TTL field encapsulated to the MPLS label header can prevent infinite loops of MPLS packets. Which of the following statements regarding the TTL field are correct?

A. MPLS provides two processing modes on the TTL field: 1. TTL in the MPLS header copies the IP TTL value when an IP packet enters the MPLS network. 2. The ingress LER sets the TTL value in the MPLS header to 255.
