The
<imp-src-id>
of the imported routes. If no routes from a particular source are to be imported, then no
additional parameters are required.
The
<filter-id>
import-policy. If there is more than one route-filter for any import-source, then the ip-
router policy import source <imp-src-id> command should be repeated for each
<filter-id>

Creating an Import Source

Import sources specify the routing protocol from which the routes are imported. The
source may be RIP or OSPF.
To create an import source, enter one of the following commands in Configure mode:
Create a RIP import destination.
Create an OSPF import destination.

Creating a Route Filter

Route policies are defined by specifying a set of filters that will match a certain route
by destination, or by destination and mask.
To create route filters, enter the following command in Configure mode:
Create a route filter.

Creating an Aggregate Route

Route aggregation is a method of generating a more general route, given the presence
of a specific route. The routing process does not perform any aggregation unless
explicitly requested. Aggregate-routes can be constructed from one or more of the
following building blocks:
• Aggregate-Destination - This component specifies the aggregate/summarized route.
It also specifies the attributes associated with the aggregate route. The preference to
be associated with an aggregate route can be specified using this component.
• Aggregate-Source - This component specifies the source of the routes contributing
to an aggregate/summarized route. It can also specify the preference to be associated
