It seems efforts related to IP address specific policies are likely doomed by the sheer size of the address space, and to be pedantic, ARP has been replaced with multicast neighbor discovery which dramatically reduces the overall traffic involved.
This has nothing to do with the number of entries required in the Neighbor Cache.
Secondly, doesn't Secure Neighbor Discovery implemented at layer 2 fully mitigate these issues? I too would be interested in hearing from Radia and Fred.
It need not. Also, think about actual deployment of SEND: for instance, last time I checked Windows Vista didn't support it. Thanks, -- Fernando Gont e-mail: fernando () gont com ar || fgont () acm org PGP Fingerprint: 7809 84F5 322E 45C7 F1C9 3945 96EE A9EF D076 FFF1
