Abstract:
This document defines a standard algorithm to temporarily postpone or
'back-off' link-state IGP Shortest Path First (SPF) computations.
This reduces the computational load and churn on IGP nodes when
multiple temporally close network events trigger multiple SPF
computations.
Having one standard algorithm improves interoperability by reducing
the probability and/or duration of transient forwarding loops during
the IGP convergence when the IGP reacts to multiple temporally close
IGP events.
