OSPF graceful shutdown

I've described the OSPF Graceful Shutdown functionality in an earlier post and got an excellent question about the implications of using OSPF stub router functionality with external routes.

The more I was digging into this issue, the more design questions I've got … and finally ended up writing a whole IP Corner article about it. You can read the in-depth discussion of design and implementation aspects of OSPF stub router functionality in the December IP Corner article: Bring your Network Closer to Five Nines with Graceful Shutdown.
