>Nasty comments on list, please, compliments by private mail ;-) A trick used in some places, such as ND, is to require the receiver to check that the hop limit is equal to 255. This ensures that the packet has not been forwarded by any router (obviously the sender also has to send it with a hop limit of 255).
Historically, a popular brand of router would forward packets with LL source. So that cannot be considered safe in general. _______________________________________________ homenet mailing list homenet@ietf.org https://www.ietf.org/mailman/listinfo/homenet
