Optimizing an OSPFv3 Network
Applicable Environment
By adjusting the OSPFv3 timer, you can change the convergence speed of an OSPFv3 network and the network overload caused by protocol packets. On low-speed links, you need to consider the delay in transmitting LSAs on the interface. By adjusting the SPF calculation interval, you can mitigate resource consumption due to frequent network changes.
You can specify the DR priority of an interface to affect the DR/BDR election in a broadcast network.
Pre-configuration Tasks
Before optimizing an OSPFv3 network, complete the configuration tasks:
- Configuring the SPF Timer
- Configuring a Route Calculation Delay to Suppress Frequent LSA Flapping
- Setting the Interval for Receiving LSAs
- Configuring an Intelligent Timer for Generating LSAs
- Disabling OSPFv3 LSA Aging Management
- Suppressing an Interface from Sending and Receiving OSPFv3 Packets
- Configuring DR Priority of an Interface
- Configuring a Stub Router
- Ignoring MTU Check on DD Packets
- Verifying the OSPFv3 Network Optimization Configuration
