Re: [dhcwg] Router option, in DHCPv6

There is the case when DHCPv6 client is a router that performs prefix 
delegation, and does not run any routing protocol. This router would 
just need a default gateway. I think setting this gateway to the 
delegating router is enough but perhaps some scenario may require an 
explicit gateway ?
