OSPV3 SPF triggers on every SPF-able event instead of using timers the way OSPFv2 does. This patch makes SPF be triggered/throttled similar to OSPFv2. It adds a command to quagga identical to the OSPFv2 equivalent to configure these timers. Summary: Signed-off-by: Dinesh Dutt <ddutt at cumulusnetworks.com> Reviewed-by: Scott Feldman <sfeldma at cumulusnetworks.com> [DL: removed reference to oa->ts_spf for rebase] [DL: killed timeval_subtract] Signed-off-by: David Lamparter <equinox@opensourcerouting.org>
