from the above I don't know if Bill have autoconfigured routers...
did you?
anyway, i guess there's a separate issue - what is the best address
to be used for BGP peering at random IXes. is it what you are
talking about?
my bet is that link-local address (for tcp endpoint address) has
the best resistance against renumber or other events, however,
there are implementations that cannot do this. also it may conflict
with Francis' BGP4+ RFC (but the RFC is not too clear about separation
between tcp/179 endpoint address, and nexthop values - at least for me)
there also are IXes that use globally-reachable IPv6 prefix, curved
out from one of the adjacent ASes. for example, NSPIXP6 uses
a /64 prefix from WIDE.
there are people using addresses that are not reachable from outside,
as i have pointed out in the following. PAIX is using a /32 got from
ISI, however, the prefix used at PAIX is not reachable from outside
if we filter routes based on 6bone routing guideline.
not sure if it is a real problem or not.
