ip ospf hello-interval
Use this command to specify the interval between hello packets.
The hello-interval is advertised in the hello packets. Configure the same hello-interval for all routers on a specific network. A shorter hello interval ensures faster detection of topological changes but results in more routing traffic.
Use the no parameter with this command to return to the default time.
