Parameter
seconds: Poll Hello interval in seconds. It ranges from 1 to 65535 and defaults to 40.
Description
Use the ospf timer poll command to configure the poll Hello packet interval on NBMA
and p2mp network.
Use the undo ospf timer poll command to restore the default poll interval.
On an NBMA or p2mp network, if a neighbor becomes invalid, Hello packet will be
transmitted at the interval of poll seconds. You can configure the poll seconds to
specify how often the interface transmits Hello packet before it establishes adjacency
with the adjacent router. Poll seconds should be no less than 3 times of Hello.
Example
# Configure to transmit poll Hello packet through interface Vlan-interface 20 every 120
seconds.
