Abstract:
This document specifies a generic mechanism that facilitates the
deployment of non-backward-compatible changes in OSPF protocol. This
mechanism allows the OSPF routers to advertise the capability of non-
backward-compatible functionality and to make the functionality
operational only when supported by all participating routers.
Depending on the functionality scope, capability advertisements must
be propagated across a link, area or autonomous system (AS). For
link and area scope functionality, Router Information Link State
Advertisement (LSA) is utilized to propagate the capability
information. For the cases when compatibility must be maintained
across the whole OSPF autonomous system, new Area Information (AI)
LSA is introduced. The AI LSA is a TLV-based analog of Indication-
LSA that is used for demand circuit functionality and described in
RFC1793.
