The metric command in the Peer menu causes Alteon to create an AS path of 3 when advertising
via BGP.

Default Redistribution and Route Aggregation Example
This example illustrates how to configure Alteon 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 16 - Default Redistribution and Route Aggregation Example, page 134
, there
are two peer routers: an internal and an external peer router. Alteon is configured to redistribute the
default routes from AS 200 to AS 135. At the same time, route aggregation condenses the number
of routes traversing from AS 135 to AS 200.
Figure 16: Default Redistribution and Route Aggregation Example
Example
1. Configure the IP interface.
2. Configure the AS number (AS 135) and router ID number (10.1.1.135).
The router ID number must be a unique number and does not have to be an IP address.
However, for convenience, this ID is typically one of IP addresses assigned in IP interfaces.
