[AusNOG] another ipv6 Q

[Skeeve Stevens]

OK... so here goes.

My opinion is that what SAGE is doing is well meaning, but ultimately
problematic.

They should not be breaking down their /32 for members to announce /48's.

The reasoning for this was a significant part of my policy proposal 083 a
couple of years ago (https://www.apnic.net/policy/proposals/prop-083)

The issue was that if I got a /32, I was not able to break it down for
announcement if I want to put part of it in a different
(non-connected/aggregated) location.  So the policy allows you to get
another block to announce in that location.

The key issue here is that SAGE's /32 allocation is from a block, where if
strict BOGON listing is used, means their member routes will be dropped.

For example, the current ipv6 BOGON list is: (
http://www.space.net/~gert/RIPE/ipv6-filters.html)

ipv6 prefix-list ipv6-ebgp-strict deny   3ffe::/16 le 128
ipv6 prefix-list ipv6-ebgp-strict permit 2001:500::/30 ge 48 le 48
ipv6 prefix-list ipv6-ebgp-strict deny   2001:db8::/32 le 128
ipv6 prefix-list ipv6-ebgp-strict permit 2001::/32
ipv6 prefix-list ipv6-ebgp-strict permit 2001::/16 ge 35 le 35
ipv6 prefix-list ipv6-ebgp-strict permit 2001::/16 ge 19 le 32
ipv6 prefix-list ipv6-ebgp-strict permit 2001:0678::/29 le 48
ipv6 prefix-list ipv6-ebgp-strict permit 2001:0c00::/23 ge 48 le 48
ipv6 prefix-list ipv6-ebgp-strict permit 2001:13c7:6000::/36 le 48
ipv6 prefix-list ipv6-ebgp-strict permit 2001:13c7:7000::/36 le 48
ipv6 prefix-list ipv6-ebgp-strict permit 2001:43f8::/29 ge 40 le 48
ipv6 prefix-list ipv6-ebgp-strict permit 2002::/16
ipv6 prefix-list ipv6-ebgp-strict permit 2003::/16 ge 19 le 32*ipv6
prefix-list ipv6-ebgp-strict permit 2400::/12 ge 19 le 32*
ipv6 prefix-list ipv6-ebgp-strict permit 2600::/12 ge 19 le 32
ipv6 prefix-list ipv6-ebgp-strict permit 2610::/23 ge 24 le 32
ipv6 prefix-list ipv6-ebgp-strict permit 2620::/23 ge 40 le 48
ipv6 prefix-list ipv6-ebgp-strict permit 2800::/12 ge 19 le 32
ipv6 prefix-list ipv6-ebgp-strict permit 2a00::/12 ge 19 le 32
ipv6 prefix-list ipv6-ebgp-strict permit 2801:0000::/24 le 48
ipv6 prefix-list ipv6-ebgp-strict permit 2c00::/12 ge 19 le 32
ipv6 prefix-list ipv6-ebgp-strict deny 0::/0 le 128

If you look at the block SAGE is in, their block, in strict form, means
anything smaller than a /32 will be dropped.

Members who get a /48 from APNIC are from a different pool, 2001 somewhere,
which has a /48 length.

So... sorry SAGE, but you pooched this one.
