How to manage Static IPs to customers

Fri May 8 15:54:23 UTC 2020

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.
