Configure the LSA minimum
repeat arrival interval
The interval set with the lsa-arrival-interval command should be smaller or
equal to the interval set with the lsa-generation-interval command.
With this feature configured, you can protect network resources and routers from
being over consumed due to frequent network changes.
Follow these steps to configure the LSA generation interval:
To do...
Enter system view
Enter OSPF view
Configure the LSA
generation interval
With this command configured, when network changes are not frequent, LSAs
are generated at the minimum-interval. If network changes become frequent, LSA
generation interval is incremented by incremental-interval¬²2
of generation times) each time a generation occurs, up to the maximum-interval.
Follow these steps to disable interfaces from sending routing information:
To do...
Enter system view
Enter OSPF view
Disable interfaces from
sending OSPF packets
Different OSPF processes can disable the same interface from sending OSPF
■
packets. Use of the silent-interface command disables only the interfaces
associated with the current process rather than interfaces associated with other
processes.
After an OSPF interface is set to silent, other interfaces on the router can still
■
advertise direct routes of the interface in Router LSAs, but no OSPF packet can
be advertised for the interface to find a neighbor. This configuration can
enhance adaptability of OSPF networking and reduce resource consumption.
