The autoconfiguration process specified in this document applies only to hosts and not routers. Since host autoconfiguration uses information advertised by routers, routers will need to be configured by some other means. However, it is expected that routers will generate link-local addresses using the mechanism described in this document. In addition, routers are expected to successfully pass the Duplicate Address Detection procedure described in this document on all addresses prior to assigning them to an interface.
Strictly speaking, routers need to be configured with prefixes as well as possibly some routing information, or at least information sufficient to run routing protocols.
It is not clear to me that their global IP addresses have to configured. It could be based on its own prefix + IID information, or am I missing something? Why is there a difference above for link-local and global addresses?
