BLADEOS 6.5.2 Application Guide
270 Chapter 19: Border Gateway Protocol BMD00220, October 2010
Default Redistribution and Route Aggregation
Example
This example shows you how to configure the switch to redistribute information from one routing
protocol to another and create an aggregate route entry in the BGP routing table to minimize the size
of the routing table.
As illustrated in Figure 29, you have two peer routers: an internal and an external peer router.
Configure the G8124 to redistribute the default routes from AS 200 to AS 135. At the same time,
configure for route aggregation to allow you to condense the number of routes traversing from AS
135 to AS 200.

1. Configure the IP interface.
2. Configure the AS number (AS 135) and router ID (10.1.1.135)
.
>> # router bgp
>> (config-router-bgp)# as 135
>> (config-router-bgp)# exit
>> #
