On our network(which isn't docsis, granted) we use PPPoE for all static IP addresses, because it allows /32 ip address allocations for all home CPE routers, upstream, the routers handle routing via ospf to change the path of where that /32 public IP goes. It allows "zero touch" moving of a customer from one PoP to another. On Fri, May 8, 2020 at 8:34 AM <edwin.mallette@gmail.com> wrote:
So in most cases I'm aware of, the cable provider did not use RIP directly to a customer-managed device. The cable operator would deploy their own managed device, implement RIP and the appropriate keychains between the operator-managed premise device and the CMTS. As for the use cases, RIP was implemented to address the specific 'recombine' use case where one day (or evening) cable customer attachments could be moved from one CMTS to another. Instrumenting that with DHCP or TR69 usually required other teams' involvement and didn't allow portability.
With IPv6 you get PD which helps immensely.

That's surprising to me, I have no intentions to do routing with our cable subscribers, that seems like a headache for both sides Today we have specific ranges within subnets from where we assign IPs to customers, my main problem that I'm trying to get around is having to change a customer static IP if their node gets splitter and I have to mode them to a different CMTS
Thanks,

Yep, it's RIP. They don't support IPv6 on this either. I've been asking for IPv6 since 2006, it's always next year.
