I was just looking around and say a major Indian provider Sify (AS9583) is
announcing /64s via BGP along with main /32 which is their allocation from
APNIC.
inet6num: 2001:0E48::/32
netname: SILNET
I see Tata Comm (Sify's upstream) is accepting /64s while Tinet (one of
other upstream) is dropping and taking only /32. Other major backbones like
HE, Level3 dropping but Telia still accepting. Pretty much mixed result.
Is it simply a misconfiguration or there is some use of announcing /64s
along with main /32?
I would hope its accidental. Most people I've spoken to won't even
consider accepting longer prefixes than /48 and will typically also
refuse to accept any prefixes where there are aggregate announces
covering them.
We're going to end up with a very nasty routing table if people start
pumping all their /64s into it.
