Quite a few times it has been mentioned to me that some peering

was wondering whether this is still the case for some ISPs, or it is
not the case anymore.
I was also wondering if it has ever been the case that IPv6 peering
agreements have required support for Type 0 Routing Header and, if
it has, whether that still happens nowadays. (I guess not, but....)
I have never seen such a requirement for IPv6.
Note also that type-0 routing headers were deprecated in RFC 5095,
last year.
The functionality provided by IPv6's Type 0 Routing Header can be
exploited in order to achieve traffic amplification over a remote
path for the purposes of generating denial-of-service traffic. This
document updates the IPv6 specification to deprecate the use of IPv6
Type 0 Routing Headers, in light of this security concern.
