Either the CPE or the provider edge device could perform a relay function. The relay function is not described as part of draft-ietf-ipv6-dns-discovery-04.txt. How, exactly would it work?
In my opinion, the relay function defeats the "zero configuration" goal of the DNS Discovery mechanism, as it requires configuration - either in the CPE or the PE device - to select that DNS forwarding should be enabled across sites and how that forwarding should take place. - Ralph At 11:25 AM 4/5/2002 +0900, [EMAIL PROTECTED] wrote: > >I think the third scenario is likely to be problematic. > > > >My understanding is that your third scenario would > >require that the customers' networks all be part of > >the same site as the ISP network - at least as far in > >as a DNS server somewhere.
