Adjusting OSPFv3 Route Selection

By adjusting OSPFv3 route selection, you can enable OSPF to meet the requirements of complex networks.

Usage Scenario

To meet the requirements of complex networks, you can adjust OSPFv3 route selection rule by configuring the following OSPFv3 route attributes:

Cost on the OSPFv3 interface
Load balancing among equal-cost routes

Pre-configuration Tasks

Before adjusting OSPFv3 route selection, complete the following tasks:

Configure IP addresses for interfaces to ensure that neighboring nodes are reachable at the network layer.
Configure basic OSPFv3 functions.

Setting the Link Cost on an OSPFv3 Interface: OSPFv3 can automatically calculate the link cost for an interface based on the interface bandwidth. You can also set the link cost for the interface.

Setting the Maximum Number of Equal-Cost Routes: Routes of the same routing protocol with the same destination and cost are called equal-cost routes, and traffic can be load-balanced among these routes.

Setting the convergence priority for OSPFv3 routes: You can adjust and optimize route selection by setting the convergence priority for OSPFv3 routes.

Configuring an OSPFv3 Interface to Automatically Adjust the Link Cost: Configuring an OSPFv3 interface to automatically adjust the link cost based on link quality facilitates route selection control and improves network reliability.

Verifying the Configuration of OSPFv3 Route Selection: After setting OSPF route attributes, verify information about OSPFv3 interfaces and the routing table.
