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 are as follows:
• Packet timer—Specified to adjust topology convergence speed and network load
• LSA delay timer—Specified especially for low-speed links
• 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.
After an interface is disabled from sending OSPFv3 packets, other routers cannot obtain any information
from the interface.
Configuration prerequisites
Before you tune and optimize OSPFv3 networks, complete the following tasks:
• Enable IPv6 packet forwarding
• Configure OSPFv3 basic functions
