What is Network convergence?
Time required to “Detect the Event”, “Propagate the Event”,” Process the Event” and “Update the Routing and Forwarding Information base” and after that routing the traffic to an alternate path during the outage of primary network path is called network convergence.
OSPF have various tool and techniques for fast convergence as below mentioned:-
• Event Detection
• Event Propagation
• Event Processing
• RIB Update
Read OSPF High Availability Techniques with SSO,NSF and NSR
I will be covering various OSPF Event Detection tools in this post:-
• Carrier Delay
• Bidirectional Forwarding Detection
• Physical Links
• IP Event Dampening
• Fast Hellos
