Abstract:
In the presence of summarization, there is a need to signal loss of
reachability to an individual prefix covered by the summary. This
enables fast convergence by steering traffic away from the node which
owns the prefix and is no longer reachable.
This document describes how to use the existing protocol mechanisms
in IS-IS and OSPF, together with the two new flags, to advertise such
prefix reachability loss.
