I have some queries around the IPv6 address assignment architecture:
i. What is the currently accepted and agreed upon provider independant address assignment policy in use by RIRs to support multihoming for ISP end-customer organizations.
E.g. I read that currently there is an IPv6 address pool reserved for provider-independant address assignment to ISP clients and the minimum agreed upon prefix-length is a /48
ii. If /48s are used for multihoming address assignment, are there any considerations given to how large it can scale to and how to control the expansion in internet route-table size?
Are there any restrictions or alternatives enforced with regards to the resulting expansion?
iii. Does it also imply that the ISPs are required to accept advertisements upto /48 from peer ISPs and to reject anything above /48 e.g. like /56 etc?
