Hi All,
Thank you for these insights. We'll look into all of these and review
again our options on how we can further proceed in our IPv6 deployment.

I've been Google-ing about if there is such a standard that sets the minimum
IPv6 advertisement on BGP. My concern is that I am running a network that
is operating on multiple sites and currently rolling out our IPv6 on the
perimeter level. Having to get our /48 allocation from our RIR, I figured
out I would it would be best for us to break down the /48 into smaller
chunks (i.e /56s) and farm it out to our sites since a single /48 will be
very big for our single site.
Hi Nathanael,
Many if not most networks set a limit at /48. Verizon was the last
player of consequence to filter at /32, and they moved to /48 a couple
years ago. A few also try to limit advertisements within ISP space
nearer to /32. Usually not at /32, but a /48 announcement within space
allocated to an ISP won't necessarily be honored.
If you have distinct networks with distinct routing policies (or can
make a reasonable claim to such) and your RIR is ARIN, you can request
a block size large enough to provide a /48 to each distinct network. A
/44 or whatever. Search through the ARIN NRPM for details. I don't
know about the other RIRs; someone in your region (Asia Pacific?) will
know.
