a single value over the domain or possible variable among

The number of L equals the number of Delegated Prefixes of
different lengths totally within a given domain, which should
be determined during IPv6 address planning.
they are equal to each other. but which determines which, in or
before the IPv6 address planning?
IMHO, I guess the length of Delegated Prefix settled in phase of
the native IPv6 address planning without considering anything
about IPv4 addressing, determines the L.
?? i suppose previously with your clarification you HAVE admitted your
consensus to my 1) ~ 4) as the logic of the operation, but now you
said "without considering anything about IPv4". may you clarify your
process with starting from the following example?
Sorry, maybe there was some misunderstanding between us.
I mean you don't need to consider IPv4 when try to decide the length of
delegated prefix to be assigned to customer. Maybe it was appropriate to
use the word "anything". ;-)
Something should be considered if you need multiple sharing ratios.
i allocate:
CE1 2001:db9:8765:4320::/60
CE2 2001:db8:7654:3210::/60
then the IPv6 address planning is finished according to your statement.
then what information should i use to determine the L for each? you
mean the IPv6 address planning is enough?
Yes.

thanks,

delegated prefix length decides PSID length (sharing ratio), or
inversely? is it not that the sharing ratio is determined by how
many CEs sharing a unique IPv4 address?
best,
