Default The hello interval is 10 seconds for P2P and broadcast interfaces, and is 30 seconds for P2MP and NBMA interfaces. Views Interface view Predefined user roles network-admin Parameters seconds: Specifies the hello interval in the range of 1 to 65535 seconds. Usage guidelines The shorter the hello interval, the faster the topology converges, and the more resources are consumed. Make sure the hello interval on two neighboring interfaces is the same. Examples # Configure the hello interval on VLAN-interface as 20 seconds. system-view [Sysname] interface vlan-interface 10 [Sysname-Vlan-interface10] ospf timer hello 20 Related commands ospf timer dead ospf timer poll Use ospf timer poll to set the poll interval on an NBMA interface. Use undo ospf timer poll to restore the default. Syntax ospf timer poll seconds undo ospf timer poll Default The poll interval is 120 seconds on an interface. Views Interface view Predefined user roles network-admin Parameters seconds: Specifies the poll interval in the range of 1 to 2147483647 seconds. Usage guidelines When an NBMA interface finds its neighbor is down, it sends hello packets at the poll interval. The poll interval must be at least four times the hello interval. 118
