Usage Guidelines
Use the hello-interval command in virtual link configuration mode to set the hello interval for OSPF across a virtual link. A shorter hello interval detects topological changes faster but causes more routing traffic. The hello interval must be the same for all devices on a virtual link.
Examples
This example shows how to configure the hello interval to 15 seconds:
