Figure 7-36. OSPF Area Aggregation Configuration window

The following fields can be set or are displayed:

ParameterDescription

Area ID	Allows the entry the OSPF Area ID
	for which the routing information will
	be aggregated. This Area ID must be
	previously defined on the switch.
Network Number	Sometimes	called	the	Network
	Address. The 32-bit number in the
	form of an IP address that uniquely
	identifies	the	network	that
	corresponds to the OSPF Area above.

Advertisement This field can be toggled between Yes and No using the space bar. It determines whether or not the selected OSPF Area will advertise it’s summary LSDB (Network-Number and Network-Mask) or not.

Route Redistribution Settings

Route redistribution allows routers on the network − that are running different routing protocols − to exchange routing information. This is accomplished by comparing the routes stored in the various router’s routing tables and assigning appropriate metrics. This information is then exchanged among the various routers according to the individual routers current routing protocol. The DES-3326 can redistribute routing information between the OSPF and RIP routing protocols to all routers on the network that are running OSPF or RIP. Routing information entered into the Static Routing Table on the local DES-3326 switch is also redistributed.
