Route Aggregation Example
The figure below shows the network configuration for the example:

In the above example Controller 1, Controller 2, and Gateway 2 (GW-2)
are running OSPF with the backbone Area. GW-2 is running OSPF on one interface
and RIPv1 on the backbone side interface. We are assuming that all the
interfaces are configured with the addresses and the routing protocol as
shown above. We have to configure route aggregation of 205.226.24.0/24
from the OSPF side to the RIP side.
- Initiate a clearVISN IP Switch Manager session to Gateway 1 (GW-1).
- Click
.
- Click the Route Aggregation link in the Routing Configuration
section.
- Enter in the Add New Aggreate edit box: 205.226.24.0.
- Enter in the Mask Length edit box: 24.
- Click
.
- Click OSPF in the New Contributing Protocol drop-down list.
- Click
.
- Click the on radio button in the Contribute All Routes from
OSPF field.
- Click
.
- Click direct in the New Contributing Protocol drop-down list.
- Click
.
- Click the on radio button in the Contribute All Routes from
direct field.
- Click
.
- Click
.
- Click
.
- Click the Route Redistribution link in the Routing Configuration
section.
- Click the Aggregates to RIP link in the Redistribution table.
- Click the on radio button in the Enable Export of Routes
from Aggregates into RIP field.
- Click
.
- Click the on radio buttion in the Export All Aggregate Routes
into RIP field.
- Click
.
- Enter in the Default Metric for Exporting Routes from Aggregates
into RIP edit box: 1.
- Click
.
If the backbone
is running OSPF as well, aggregation can be done only by configuring the
205.226.24.0 network in a different OSPF Area.
