Re: [v6ops] reclassify 464XLAT as standard instead of info

[JORDI PALET MARTINEZ <[e-mail]>]

You’re right, that’s why I said quick thought because I’ve seen operators doing that actually (two APNs one for broadband LTE, one for smartphones) ;-)

So, a single APN, provides by default a /64. Then if it is a broadband router starts DHCPv6-PD (not sure then if NO need to use RFC6603 for excluding the WAN link if the initial “default” /64 was already used as well for the WAN link).

Regards,
Jordi

    The claim that you need multiple APNs for that is not logical.
    
    The basic function "assign a /64 for each PDP" is 3GPP standard, any APN
    needs to do that (and that's the /64 you use for 64share).
    
    The extra function "DHCPv6-PD" is conceptually totally independent - you
    need an IPv6 capable link, nothing else, and whether or not a /64 has been
    assigned is not relevant for PD.  
    
    Now, if a given *vendor* can only turn on one or the other on their gear 
    is an implementation choice, and that REALLY doesn't belong here - if at
    all, it's a 3GPP standardization topic ("if you add DHCPv6PD, you MUST
    continue to provide a /64 for each subscriber").
