Yes, sorry. The question should have been: Has IPv6 Type 0 Routing
Header ever been a requirement in v6 peering agreements?
(In any case, I guess Type 0 Routing Header could still be used, in
the same way that v4 source-routing was still being used even after
many IP implementations had decided to filter it by default?)
