Ralph,
The text in question may be in RFC 3633, section 12.1, which requires that the valid lifetime for the prefix in the RA must be no later than the valid lifetime in the IA_PD.
Ah. The full text says: ... the requesting router MUST set the valid lifetime in those advertisements to be no later than the valid lifetime specified in the IA_PD Prefix option. A requesting router MAY use the preferred lifetime specified in the IA_PD Prefix option. I think this is fine, and allows the implementation to do the sensible thing. You can put in a smaller time. You can use the exact lease time. You would only get into trouble if the PD lease times where insanely small. Fixing that requires the operator to notice, and cannot be fixed in IETF specifications. In any case, we don't have a huge amount of PD deployment yet, so additional practical guidance on what kind of values to use within the rules specified above can be useful and might have an impact on what people actually do. Personally, I think its rather obvious, but I could of course be missing something. (I'm walking to the meeting site now. I had a day job conference call in the morning... Hope you solved all the problems in the morning session already :-) Jari _______________________________________________ homenet mailing list [email protected] https://www.ietf.org/mailman/listinfo/homenet
