Mikael,

>might be different from the default-route gw?

It's the IPv6 default router for the DHCPv6 client that sends a RA with
the M-bit set and seeing such an RA the client initiates DHCPv6.  Or the
client could initiate DHCPv6 even on receiving an RA with the M-bit
cleared.  But the fact still remains that the DHCPv6 client did receive
an RA from the IPv6 first-hop router to the client.  The client is
supposed to perform router discovery and send RS.  The RA lets the
client know what the default router is.  If I missed anything, perhaps
if you could please draw a diagram and let us know what specific use
case I missed.

Thanks,

Hemant
