Tuning and Optimizing OSPFv3 Networks
This section describes configurations of OSPFv3 timers, interface DR priority, MTU check ignorance for
DD packets, and disabling interfaces from sending OSPFv3 packets.
OSPFv3 timers:
z
Packet timer: Specified to adjust topology convergence speed and network load
z
LSA delay timer: Specified especially for low-speed links
z
SPF timer: Specified to protect networks from being over-loaded due to frequent network changes.
For a broadcast network, you can configure DR priorities for interfaces to affect DR/BDR election.
By disabling an interface from sending OSPFv3 packets, you can make other routers on the network
obtain no information from the interface.
