WebGreg is right, TTL (or better expressed as "hops to live" as IPv6 header states it more precise) does not care about AS-boundaries. Whenever a packet will be changing segments (in turn go through a router) TTL will be counted down. As I said in my first post, The internet is better organized as many may think. Web21. You've got a circular route in your networking configurations, check your routing tables on the involved devices. "TTL expired in transit" is related to the TTL value of the packet; every router it passes through lowers it by one. If it hits 0, the packet is dropped and an ICMP message (the 'expired in transit' message) is sent to the sender.
