Usage Guidelines

Usage Scenario

On an NBMA network, after a device's neighbor becomes invalid, the device periodically sends Hello packets to the neighbor according to the poll interval set in the ospf timer poll command. The poll interval should be at least 4 times that of the Hello interval.

Precautions

OSPF does not support the configuration on a null interface.
