It's case happened at my company, when we had our core router rebooted. Though we have the secondary router, one of the layer 3 switch directly connected to both core routers failed to change its routing paths (what we actually obseved is no traffic on the secondary link to the secondary router), while other layer 3 switches with same setup anh configuration succeeded. After the primary core rebooted, we did check and saw no problem with OSPF neighborship and routing on the secondary router.
Due to confidentiality I can't post any diagram or config over here, but I'm pretty sure that connection and configuration are simply correct (as aslo confirmed from Cisco TAC)
Just want to ask if you guys ever experienced the same incident and in case routing configuration is correct, what probably the root cause is.
