Step 5. Inject a default route. 6. Filter redistributed routes. Command default-route-advertise [ always | cost value | type type | route-policy route-policy-name ] * filter-policy { acl6-number | ipv6-prefix ipv6-prefix-name } export [ ospfv3 process-id | ripng process-id | bgp4+ | direct | static ] Remarks Optional. Not injected by default. Optional. Not configured by default. 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. The following are OSPFv3 timers: • 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 overloaded due to frequent network changes. For a broadcast network, you can configure DR priorities for interfaces to affect DR or 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. Configuring OSPFv3 timers Step 1. Enter system view. 2. Enter interface view. Command system-view interface interface-type interface-number 3. Configure the hello interval. ospfv3 timer hello seconds [ instance instance-id ] 4. Specify the poll interval. ospfv3 timer poll seconds [ instance instance-id ] Remarks N/A N/A Optional. By default, the hello interval on P2P, broadcast interfaces is 10 seconds. Optional. By default, the poll interval is 120 seconds. 215
