Thank you, I forgot to think about NS and NA. One more question, If I got the /64 mask from ISP and implement as below. Theoretically, is it work?
Normal Situation: work fine IPv6 Internet ----- ISP (2001:db8:a:1::1/64) ----- (2001:db8:a:1::2/64) MyPC My Implementation: is it possible? IPv6 Internet ----- ISP (2001:db8:a:1::1/64) ----- (2001:db8:a:1:0::2/80) MyRouter (2001:db8:a:1:a::1/80) ----- (L2 SWITCH) ----- (2001:db8:a:1:a::2/80) MyPCs So from my router will also be IPv6 network with Global Unicast address. --Te On Wed, Jun 18, 2014 at 1:14 PM, Eric Vyncke (evyncke) <evyn...@cisco.com> wrote: > Not sure whether I fully understand the question in all details, but: > > 1. on a LAN/WLAN (basically where NS/NA is required to work, = > broadcast domain with MAC addresses), the use of a /64 prefix is > recommended > 2.
