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 min-
imize the size of the routing table.
As illustrated in
Configure the GbE Switch Module 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.
Figure 11-4 Route Aggregation and Default Route Redistribution
1. Configure the IP interface.
2. Configure the AS number (AS 135) and router ID number (10.1.1.135)
>> # /cfg/l3/bgp
>> Border Gateway Protocol# as 135
>> Border Gateway Protocol# .. /rtrid 10.1.1.135(Specify a router ID number)
