DES-3326 Layer 3 Fast Ethernet Switch User’s Guide
Figure 7-36. OSPF Area Aggregation Configuration window
The following fields can be set or are displayed:
Parameter Description
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.
