The hello interval defaults to 10s for P2P and Broadcast interfaces, and defaults to 30s for P2MP and 

NBMA interfaces. 

The shorter the hello interval is, the faster the topology converges and the more resources are 

consumed. Make sure the hello interval on two neighboring interfaces is the same. 

This configuration is not supported on the null interface.

seconds: Poll interval in seconds, in the range 1 to 2147483647. 

Use the ospf timer poll command to set the poll interval on an NBMA interface. 

Use the undo ospf timer poll command to restore the default value. 

By default, the poll interval is 120s. 

When an NBMA interface finds its neighbor is down, it will send hello packets at the poll interval.  

The poll interval is at least four times the hello interval. 

This configuration is not supported on the null interface.

# Set the poll timer interval on the current interface to 130 seconds.
