Summary of OSPFv3 Configuration Tasks
After basic OSPFv3 functions are configured, you can build a basic OSPFv3 network. If other OSPFv3 functions are required, configure them according to reference sections.
Table 6-6 describes the OSPFv3 configuration tasks.
Scenario |
Description |
Task |
---|---|---|
Constructing a basic OSPFv3 network |
Before configuring OSPFv3, you must enable the OSPFv3 process and specify the router ID. Other OSPFv3 functions then can be configured or take effect. In practical applications, establishing or maintaining OSPFv3 neighbor relationships is an important precondition for the construction of OSPFv3 networks. By implementing the configuration tasks in this section, you can:
|
|
Configuring OSPFv3 special area attributes |
After the basic OSPFv3 network is constructed, OSPFv3 special area attributes can be flexibly used to deploy the OSPFv3 network according to actual needs.
|
|
Configuring OSPFv3 route attributes |
In practical applications, to meet the requirements of complex network environment, configure the OSPFv3 route attributes to change the OSPFv3 route selection policies. |
|
Controlling OSPFv3 routing information |
In practical applications, to meet the network requirements, configure filtering of received and advertised routes and route aggregation, and control the number of external routes from the LSDB to implement accurate control of OSPFv3 routing information. |
|
Adjusting and optimizing OSPFv3 networks |
Change the OSPFv3 packet timer to adjust the OSPFv3 network convergence rate and network load brought by protocol packets. On some low-rate links, the delay of LSA transmission by interfaces must be considered. Adjust the SPF calculation interval to restrict resource consumption caused by frequent network changes. |
|
Configuring OSPFv3 GR |
To prevent route flapping and interruption of traffic forwarding caused by OSPFv3 restart, enable the OSPFv3 GR features. After OSPFv3 is restarted, the GR Restarter and the GR Helper re-establish the neighbor relationship, exchange routing information, synchronize the database, and update the routing table and forwarding table. This implements OSPFv3 fast convergence. |
|
Improving OSPFv3 network security |
On networks that require high security, the OSPFv3 GTSM and authentication method can be configured to improve OSPFv3 network security.
|
|
Configuring the OSPFv3 network management function |
OSPFv3 supports the network management function. You can bind OSPFv3 MIB to a process. In addition, OSPFv3 also supports fault and log functions. |
