Default values for this field are specific to the softwire mechanism being implemented and are defined in the relevant specification document. that looks fine. updated. > Good spot on the WKP exclusion. Before the lw4o6 draft was updated to reference map-dhcp for configuration, the port configuration was described in sun-dhc-port-set-option, which also stated that the WKPs should not be assigned. This advice got lost when changing to reference map-dhcp. I’ll make a suggested text update for the lw4o6 draft to fix this. Does that work for you? yes, that would be good. cheers, Ole
