At the time I wrote down Babel, I decided that given that we have link-local addresses that are securely scoped to a single link, the TTL hack is not necessary. A workaround to the issue you describe would be to check the destination address of Babel/HNCP packets in addition to the source address, and rejecting a packet if the destination address is not in one of fe80::/64 or ff02::/112. If we did that, would the TTL hack still hold any value? -- Juliusz _______________________________________________ homenet mailing list homenet@ietf.org https://www.ietf.org/mailman/listinfo/homenet
