[ovs-dev] [ovs-discuss][ovn][dhcp]Could ovn remove restriction of option 3(router)

[Dong Jun]

An router IP MUST be set to dhcp v4 option for option 3, but not all 
subnet do have a gateway IP. Furthermore,  if i set 0.0.0.0 to option as 
a tradeoff, the VM can obtain client ip and a gateway error log occurred 
meanwhile.

It seems that it's not a  restriction in RFC 2132, as comparison dnsmaq 
can offer a no-router-ip option.

So could ovn remove this restriction or is there anther way to meet the 
requirement?
