DR.

5.2.14 Setting the Cost for Sending Packets on an Interface

You can set the cost for sending packets on different interfaces so that the route
calculation is affected.
Do as follows in interface view.

Restore the default cost for sending packets on the
interface.

5.2.15 Setting SPF Calculation Interval for OSPF

Whenever the LSDB of OSPF changes, the shortest path should be recalculated. In
this way, enormous resources are consumed and the operation efficiency of the router
is reduced. Adjusting the Shortest Path First (SPF) calculation interval, however, can
restrain the resource consumption due to frequent network changes.
Do as follows in OSPF view.
Table 5-21 Setting the SPF calculation interval
Set the SPF calculation interval.
Restore the SPF calculation interval.

5.2.16 Setting an Interval Required for Sending LSU Packets

Trans-delay should be added to the aging time of the LSA (Link State Advertise) in an
LSU (Link State Update) packet. Setting the parameter like this mainly considers the
time duration that the interface requires for sending the packet. In low speed network,
this setting is more important.
