RFC 6164 does not define operational practice or a recommended way of designing your network or configuring your router(s). All RFC 6164 says is essentially that some networks do want to use longer than 64-bit prefixes and there are some valid reasons, explains what motivates some operators to do so, and adds recommendations that routers must allow assignment of /127 prefixes on P-t-P inter-router links and disable subnet-router anycast when in use. In other words... if you are implementing an IPv6 router, RFC 6164 will assist you by giving you technical recommendations that you implement the capability for /127 prefixes on your router, with motiviations listed that will help you decide whether to include support for /127 inter-router links or not. -- -JH
