What subnet mask you are people using for point to point IPs between two
ASes? Specially with IPv6, We have a transit provider who wants us to use
/64 which does not make sense for this purpose. isn=E2=80=99t it recommende=
d to use
/127 as per RFC 6164 like /30 and /31 are common for IPv4.
You can just ignore that and configure it as a /126 from your end. Does not
matter if they configure their end as a /64 assuming the actual assigned
addresses fit in a /126.
