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 1 describes the OSPFv3 configuration tasks.
Scenario |
Description |
Task |
|---|---|---|
Constructing a basic OSPFv3 network |
Enable the OSPFv3 process and specify the router ID before configuring OSPFv3. After this is complete, other OSPFv3 functions can be configured or take effect. |
|
Configuring OSPFv3 special area attributes |
You can flexibly use OSPFv3 special area attributes to deploy the network according to actual requirements. The special areas are as follows: |
|
Configuring OSPFv3 route attributes |
You can configure the OSPFv3 route attributes to change OSPFv3 route selection policies. This can help meet the requirements of complex network environments. |
|
Controlling OSPFv3 routing information |
You can configure route summarization as well as the filtering of received and advertised routes. Route summarization lowers the number of external routes in the LSDB and provides accurate control of OSPFv3 routing information. |
|
Adjusting and optimizing OSPFv3 networks |
You can change the OSPFv3 packet timer to adjust the OSPFv3 network convergence rate and network load caused by protocol packets. On some low-rate links, the delay of LSA transmission by interfaces must be taken into account. You can adjust the Shortest Path First (SPF) calculation interval to restrict resource consumption caused by frequent network changes. |
|
Configuring OSPFv3 GR |
You can enable OSPFv3 GR features to prevent route flapping and interruption of traffic forwarding caused by an OSPFv3 restart. After OSPFv3 is restarted, the GR restarter and the GR helper reestablish neighbor relationships, exchange routing information, synchronize the database, and update the routing and forwarding tables. This implements fast OSPFv3 convergence. |
|
Improving OSPFv3 network security |
On networks that require high security, you can configure the OSPFv3 Generalized TTL Security Mechanism (GTSM) and authentication mode to improve network security. |
|
Configuring the OSPFv3 network management function |
OSPFv3 supports the network management function as well as fault and log functions. You can bind the OSPFv3 management information base (MIB) to a process to use these functions. |
