Hi Shree, Sorry for the late reply because I was on a bussiness trip yesterday.
The reason I propose to extend RA is because that DHCPv6 may not be available in some scenario. If the extension is simple enough, it may be worthy.

With your comments, I realize that the User Class Option defined in RFC 3004 allows much flexibility because the User Class value is an opaque field and implementation specific. Without a centralized control point, the value of the User Class can not be well maintained. So I agree with you that the User Class Option is better managed in the centralized approach like DHCPv6 and the User Class can not be introduced to RA in the same way as defined in RFC 3004. So I think if we would like to extend the RA or PIO option, we would need unified or global values for the service types (not using the User Class in this case). That is to say, the service types associated with the prefix should be allocated by IANA. What do you think? Would this approach be better? Thanks again!
