Title: ipv6 dns cannot get from ipv6 dhcp pool in router
Post by: phython on July 19, 2012, 09:00:46 PM

hi all,

i have configure dhcp pool for router. Router will act as dhcpv6 server to deliver dhcpv6 address to client. my question is i failed to deliver dns-server to my client. does anyone know what the problem? can i just simply use google ipv6 dns server as my dns server? my ipv6 client also cannot get ipv6 default gateway.

Gateway doesn't come from DHCP, it comes from the router doing RA's.

As far as clients not picking up your dns settings, what kind of clients?

hi jtcloe,

client is window pc. Do you see my configuration have missed out something?
