DES-3326 Layer 3 Fast Ethernet Switch User’s Guide

Status

Displays the current status (UP or

 

DOWN) of the corresponding OSPF

 

Virtual Interface.

 

 

Area Aggregation Configuration

Area Aggregation allows all of the routing information that may be contained within an area to be aggregated into a summary LSDB advertisement of just the network address and subnet mask. This allows for a reduction in the volume of LSDB advertisement traffic as well as a reduction in the memory overhead in the switch used to maintain routing tables.

To aggregate routing information contained within an OSPF area, highlight Area Aggregation Configuration from the Setup OSPF menu and press Enter.

The following fields can be set:

ParameterDescription

Action:<Add/Modify

This field can be toggled using the space bar between

>

 

Add/Modify and Delete. Add/Modify allows for the creation

 

 

of a new OSPF Area Aggregation or changes to an existing

 

 

OSPF Area Aggregation. Delete allows for the deletion of an

 

 

existing OSPF Area Aggregation.

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.
