Creating An Import Source; Creating A Route Filter - Cabletron Systems IA1100 User's Reference Manual

If you want to create a complex route-filter, and you intend to use that route-filter in
several import policies, then the first method is recommended. It you do not have
complex filter requirements, then use the second method.
After you create one or more building blocks, they are tied together by the ip-router
policy import command.
To create route import policies, enter the following command in Configure mode:
Create an import policy.
The <imp-src-id> is the identifier of the import-source that determines the source of the
imported routes. If no routes from a particular source are to be imported, then no
additional parameters are required.
The <filter-id>, if specified, is the identifier of the route-filter associated with this 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.
