With OSPF delay advertisement, intra-domain link delay information can be collected and flooded.
Traditional path computation algorithms compute the optimal path to a destination address based on costs. However, the path computed in this way may not have the minimum delay. For services that have stringent requirements on delay, path computation can be performed based on the delay rather than on the cost to ensure that service traffic is transmitted along the path with the minimum delay. After OSPF delay advertisement is configured, OSPF collects and floods intra-domain link delay information and reports the information to the controller through BGP-LS. The controller then computes paths on the P2P network based on delay constraints.
The system view is displayed.
An OSPF process is created, and the OSPF view is displayed.
process-id specifies an OSPF process. If the process-id parameter is not specified, the system creates process 1 by default.
The Opaque capability is enabled on the device.
Delay advertisement is enabled.
The configuration is committed.
After the configuration is complete, verify the configuration.
Run the display ospf interface verbose command to check information about OSPF-enabled interfaces.
