Usage Guidelines
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.
This command requires the LAN Base Services license.
Examples
This example shows how to configure the hello interval to 15 seconds:
switch# configure terminal
switch(config)# router ospf 202
switch(config-router)# ip ospf area 99 virtual-link 192.0.2.4
switch(config-router-vlink)# hello-interval 15
switch(config-router-vlink)#
