Syntax

View
Interface view
Parameters
seconds
: Hello interval in seconds, in the range 1 to 65535.
Description
Use the
ospf timer hello
command to set the hello interval on an interface.
Use the
undo ospf timer hello
command to restore the default hello interval on an
interface.
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.
