Hi All,
Please correct or comment on following:
Ospf commad "local-rib-criteria inter-area-summary" sheds light on a check ospf performs when regenerating inter area summaries into adjacent areas. Command seems to indicate that default is for abr to check global route table for presence of inter summary route as O IA route.
If present as an ospf route O IA then pass this check and regenerate to adjacent areas.
If present as bgp or eigrp route (or not present at all) then dont advertise to adjacent areas.
This command alters this behavior to check local ospf rib vice global rib and permits re-generations of lsa3 regardless of state in global rib.
Cisco config guide talks about usage to speed up ospf convergence.
Best Regards
