IESG Note:
This document defines mechanisms for informing a set of routers of
renumbering operations they are to perform, including a mode of
operation in environments in which the exact number of routers is
unknown. Reliably informing all routers when the actual number of
routers is unknown is a difficult problem. Implementation and
operational experience will be needed to fully understand the
applicabilty and scalability aspects of the mechanisms defined in
this document when the number of routers is unknown.
Abstract
IPv6 Neighbor Discovery and Address Autoconfiguration conveniently
make initial assignments of address prefixes to hosts. Aside from
the problem of connection survival across a renumbering event, these
two mechanisms also simplify the reconfiguration of hosts when the
set of valid prefixes changes.
This document defines a mechanism called Router Renumbering ("RR")
which allows address prefixes on routers to be configured and
reconfigured almost as easily as the combination of Neighbor
Discovery and Address Autoconfiguration works for hosts. It provides
a means for a network manager to make updates to the prefixes used by
and advertised by IPv6 routers throughout a site.
