IP address is required machine to machine communications, and routing protocol is using to provide this IP address reachability.
Limited shared resources, IP address, is required between router and router's link,too. Thus we are using 30 bit mask which has 2 hosts , broadcast/network adress and also /31(RFC3021).Router provides IP reachability but it is requres limited resouces IP address , it looks a lit bit funny, so for the IPv6 routing is using link-local address.In the data center, the design which uses the characteristics of the IPv6 routing and RFC5549 is a little bit increasing.
This presentation will share information of applicability of the RFC5309 P2P over LAN, the technic of how to distribute /32 or /128 host route in the network, consideration point of operation for only use link local address(RFC7404) and some related topic of IP addresses and also will discuss with operators within JANOG45 attendees.
