Re: Stop the hello in OSPF

 Suppressed Periodic Hellos

When an OSPF demand circuit is configured on a link, the periodic OSPF
hellos are suppressed. Periodic hellos are suppressed only on a
point-to-point and point-to-multipoint network type. *On any other network
type, OSPF hellos are still sent over the interface.*
