A while ago I've described a scenario where OSPF behaves like a distance-vector protocol
, including creating temporary routing black holes. If you think this behavior might affect your network, it's best you test the details in a controlled lab environment. Our OSPF quick learning module
will tell you how to tweak the OSPF parameters and how to prevent IP prefix reappearance in the original area. The blended solution also includes a remote lab exercise, where you can test the IOS behavior on actual routers.
E-lessons are subscription-based; you can repeat each module in the lesson (including the lab) as many times as needed.
