[dhcwg] DHCPv6 router option

[Iljitsch van Beijnum <iljitsch at muada.com>]

I very strongly disagree with draft-droms-dhc-dhcpv6-default- 
router-00.txt in its current form.

The ability to put a random address in DHCPv6 that is supposed to be a  
router, but which in actuality may or may not be a working router is a  
huge step backwards from the current situation where routers  
themselves announce their existance and therefore there is a  
reasonable expectation that they are, in fact, working routers.

What I suggest is that you change the draft such that router  
advertisements are still required, but the DHCPv6 option indicates  
which of the routers that advertise their presence a host should use.

I'm also missing any discussion about dead neighbor detection, which  
would normally make a host select a different default router.
