Ospf Timer Poll - 3Com S7906E Command Reference Manual

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.
