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.
