You mean like the lack of Default Router in DHCPv6?

Don't get me wrong. I love RA. However, it is NOT a universal tool, and there are cases where Default Router via DHCPv6 would be more appropriate and easier to manage.

Case in point. If I hand out IA_NA or IA_TA to directly connected DSL hosts or CPEs, I have no need of RA. In addition, the load on my router is increased by having to send RA to 3000+ interfaces, something that is absolutely not necessary in my deployment. I would even go as far to say that Default Router would be a good stateless option to hand out along with the DNS servers when customers do SLAAC with me.

I have also now seen 2 different vendor DSL modems which when not using PPPoE require a manually entered default router (ie, no RA support).
