how to set DNS server in announce

[brianjmurrell]

My 14.07 OpenWRT router is not my DNS server but rather another machine in my network is. But I cannot seem to get odhcpd to announce that other server (or announce nothing). It keeps announcing itself as the DNS server. I have tried any number of "dns" options in:

config odhcpd 'odhcpd'

but I cannot get it to change behaviour. I have tried:
option dns ''

option dns 'fd31:aeb1:48df:0:21f:c6ff:fec4:926a'

list dns 'fd31:aeb1:48df:0:21f:c6ff:fec4:926a'

But I still keep getting the OpenWRT router in the RA.

Any ideas?

NM. I just noticed I need to set those options in the config dhcp section
