Configuring OSPF Network Optimization 303
n
The interval set with the lsa-arrival-interval command should be smaller or
equal to the interval set with the lsa-generation-interval command.
Specifying the LSA
Generation Interval
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:
n
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
n-2
(n is the number
of generation times) each time a generation occurs, up to the maximum-interval.
Disabling Interfaces
from Sending OSPF
Packets
Follow these steps to disable interfaces from sending routing information:
n
■ 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.
