Difference between NSF, NSR and Graceful-restart

     Hi All,

I am confused about the aforementioned concepts, it would be helpful if some one can explain or point me to relevant documentation. Also i would like to know when do we use NSF comapared to NSR specially when using the routing protocols OSPF and BGP and which one is the better option. Further are there any dependencies like the partner node should be NSF or NSR aware.

I am currently using ASR9010 as the service provider PS backbone.

Best Regards

Saikat Chakraborty
