PCP requests go to the PCP server the client chooses. PCP servers can currently only be advertised using DHCP. If there are multiple PCP servers, the client has to register with all of them. A PCP server should know whether it makes sense to register a port/address combination with it. > How does it work if there are multiple layers of router? I believe that the PCP server on the inner router communicates with the PCP server on the outer router, but I’d have to double check.

It should be assumed to be the rule, so that if it is the rule, it is handled correctly.

I don’t think there’s any need for the IID to be persistent. Make-before-break is accomplished by deprecating the old prefix when the new prefix is added. This is trivial to do; whether it is in fact done is a different matter. I think that at present the client would have to notice that it’s happened. _______________________________________________ homenet mailing list homenet@ietf.org https://www.ietf.org/mailman/listinfo/homenet
