In that way, we can use DHCPv4 as is, no additional options need inventing. > If defining DHCPv6 option, the router should have an global > IPv4 address as well as IPv6 tunnel endpoint address at the > same time, and should configure IPv6 tunnel and attach IPv4 > global address to it. > > In the former case, the router has to decide whether it uses > IPv4 global address or not by the reply from the DHCPv4 server > that may not exist in the network.

DS-Lite avoids IPv4 provision in the SP network, so it is hard for us to assume a DHCPv4 server would be there. > So, as you suggest, it may be better to use DHCPv6. ;-) Thanks, washam _______________________________________________ Softwires mailing list [email protected] https://www.ietf.org/mailman/listinfo/softwires
