I am confused with freeBSD implementation and RFC2460 specification for Destination options. My interpretation from RFC2460 is that, If a packet consists of hop-by-hop and destination extension headers, destination header should be inserted inside AH. i.e., hop + AH + dst. But freeBSD implementation is the other way, i.e., hop + dst + AH. which is the correct way of implementation according to RFC2460? Please let me know, if my interpretation is wrong. Also, let me know AH insertion place in the following cases. 1. hop + dst=20 2. hop + dst + route 3. hop + dst + route + dst 4. hop + dst + dst 5. hop + dst + dst + route + route 6. hop + dst + dst + route + route + dst + dst 7. hop + dst + dst + route + dst + route + dst + dst Any help/suggestion is greatly appreciated. Thanks, Srinivas. --=20 Srinivas Goud "Everything is Nicer when shared with a Friend"
