Mikael,
[changing subject as this has departed from discussing the RS mark draft]
I think the technical issue there is that ND and RA were designed as a
package, and you certainly can't run without ND.
Well, the DHCPv6 standard can be changed to hand out information so ND isn't
needed. This is what I had in mind. This would remove the need for the whole
RA/ND/RS package completely.
I don't understand what you mean when you say ND isn't needed.
basic ND has this set of functions:
Router Discovery
Prefix Discovery
Parameter Discovery
Address Autoconfiguration
Address resolution
Next-hop determination
Neighbor Unreachability Detection
Duplicate Address Detection
Redirect
are you proposing that DHCPv6 is extended to cover all of them?
if not, then which ones?
This question is difficult, because the list is long and you basically
ask a value DHCPv6vsND for each item.
DAD: Maybe one would make DHCPv6 to distribute an address _and_ the
result of DADing directly?
If DHCPv6 does Prefix Discovery, then it would like to make sure the
prefix it offers is different than that of Prefix Delegation - different
prefixes of a different concept.
Parameter Discovery: does DHCPv6 offer already MTU and Hop Limit values?
If not then it would make sense to offer it.
Address Resolution: no, DHCPv6 would not be good to resolve IP address
to MAC address. It's essentially a linkscoped operation.
...
Redirect: it's essentially a linkscoped operation. A DHCPv6 Server on
another link would have a hard time hearing the causes which provoke
redirects.
There's another line appearing hidden through the items in the above list:
the default route
I'd like the IPv6 default route delivered by DHCPv6, in tandem with ND
(that RA 'M' flag made sense).
Alex
cheers,
Ole
