first hop, I'm pretty sure you wouldn't trust it to dictate which
address to use anyway (without further checks).

Hi Tim,

Greg,
Backward compatability shouldn't really be a problem.
Hosts which are doing RFC2461 Router Discovery
will understand RAs with options or bits in them
indicating solicitation or completeness, but just not
be able to access the improved function.
If a host that

Hi Tim,

All,
Suggested resolution:
- Introduce a new code (1) in the router solicitation
and advertisement. When a host sends an RS with code = 1
it requests that the RA include all prefixses valid on
that link. Similarly, when a router sends an RA with code=1
it means that

Rather than adding new code to verify this, shouldn't we just warn about

Hi Hesham and Pekka,
I'm not sure if this is the same issue
(looks somewhat related), but RFC2461
allows any source address for an RS message,
and only link-local response (doesn't match
scopes).
The difficulty comes when an RS comes from a global
source address which is not directly connected to
s the implementation of DHC on routers
doesn't need to be terribly sophisticated, and
avoids lumping generic configuration into
a service which is addressing and routing oriented
(Router Advertisement).
