The same behavior that a router would display with an IP packet that had an expiring TTL is seen when a labeled packet is received with a TTL of 1, in which case the receiving LSR drops the packet and sends an ICMP message stating that the time limit has been reached (type 11, code 0) to the IP packets originator.5 Jan 2007
What is TTL 255 in ping

Who sets the TTL value
