Hi Denis, The Babel neighbour sensing mechanism is exactly as you describe: if a given IP address hasn't sent you a Hello, it doesn't exist, and all packets from it are silently dropped until it sends a Hello. This is by design.
You are correct that an IHU does not carry explicit information about individual hellos, but just a single integer that summarises the link quality. That's by design, and that's the reason why IHU is called IHU, not Ack. I haven't been able to understand the attack that you outline just from looking at the slides, so I suggest we discuss it after you've done your presentation. -- Juliusz _______________________________________________ Babel-users mailing list Babel-users@lists.alioth.debian.org http://lists.alioth.debian.org/cgi-bin/mailman/listinfo/babel-users
