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’t it
recommended to use /127 as per RFC 6164 like /30 and /31 are common
for IPv4.
Whatever you want.
I was thinking, if someone is using RFC7404 for point to point IP
between two ASes and establish BGP over link local addresses. This
way you have your own IP space on your router and transit provider
does not have to allocate IP space for point to point interface
between two ASes. In traceroutes you would see only loopback IP
address with GUA assigned from your allocated routable address
space. Remotely DDoS to this link isn’t possible this way. Thoughts?
If you can protect the loopback IP from DDoS you can equally protect
linknet IPs.
