H Commands
This chapter describes the Cisco NX-OS Open Shortest Path First (OSPF) commands that begin with H.
hello-interval (OSPF virtual link)
To specify the interval between hello packets that Cisco NX-OS sends on an Open Shortest Path First (OSPF) virtual link, use the hello-interval command. To return to the default setting, use the no form of this command.
Command ModesVirtual link configuration mode
Usage GuidelinesUse 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.
