Hey, Usually numbering backbone routers with a 10/8 is not a necessary practice. Any backbone routers communicating with the outside world are marked category three and should have globally unique IP numbers. Plus, if you are an ISP (in which it looks like you are..), it will help others on pu

Generally it is not prohibited by the RFC, but it is bad form if you send out ICMP that originates from 10space to places outside your network. As such, it's generally bad form to use these numbers on intefaces in the backbone, since those interfaces are likely to show up in ICMP time exceeded mes

Very old thread! Private hosts can communicate with all other hosts inside the enterprise, both public and private. However, they cannot have IP connectivity to any host outside of the enterprise. All other hosts will be public and will use globally unique address space assigned b

Hi All, I am trying to collect information about using RFC 1918 space on an ISP backbone. I have read the RFC several times, and I don't see where it says that you cannot use 10/8 space to number your backbone links (/30s). I know this is an old thread that has been rehashed several times,
