Default Redistribution And Route Aggregation Example - Lenovo RackSwitch G8264 Application Manual

Default Redistribution and Route Aggregation Example

1. Configure the IP interface.
2. Configure the AS number (AS 135) and router ID (10.1.1.135)
3. Configure internal peer router 1 and external peer router 2 with IPv4 addresses.
4. Configure redistribution for Peer 1.

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
peer router. Configure the G8264 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.
