And there are other platforms, e.g. Juniper M/MX/T, where there is no concept of "punt a packet to software to perform a forwarding decision". The packet is either forwarded in hardware, or dropped. IPv6 prefixes > 64 bit are handled like any other IPv6 prefixes, i.e. they are forwarded in hardware. Steinar Haug, Nethelp consulting, [email protected]
