So if a router sends a packet with a TTL of 1, the next router receives it, decrements it and then drops it before sending it because TTL is now 0. <br /><br />I have never seen an application that would send a packet with TTL 0. I don't know if it is valid to do so, although maybe if you only wanted connected hosts to see it...then I think you still need it to be 1. But that would be a good lab :)deadhead blueshttps://www.blogger.com/profile/10566569168999502387noreply@blogger.comtag:blogger.com,1999:blog-6193417800921617897.post-75528177948499171702010-01-25T01:57:45.352-08:002010-01-25T01:57:45.352-08:00Interesting - I'm just experiencing some odd i...Interesting - I'm just experiencing some odd issues with mcast whilst trying to play with scopes (on Mapping Agent). In your experience, have you consistently found multicast with TTL 0 will send or is this technically an illegal packet?ahttps://www.blogger.com/profile/14552404554663068562noreply@blogger.com
