View
Interface view
Parameter
seconds: Specifies the poll Hello messages interval, ranging from 1 to 65535 and
measured in seconds. By default, the value is 40 seconds.
Description
Use the ospf timer poll command to configure the poll Hello message interval on
nbma and p2mp network.
Use the undo ospf timer poll command to restore the default value.
On the nbma and p2mp network, if a neighbor is invalid, the Hello message will be
transmitted regularly according to the poll seconds. You can configure the poll
seconds to specify how often the interface transmits Hello messages before it
establishes adjacency with the adjacent router.
You are recommended to set the poll timer longer than the hello timer.
