5. Link a network filter to the access list.
6. Enable the network filter.
7. Specify the IP address and mask for the network filter.
Optional Parameters for Route Maps
Set the following optional parameters (metric type and metric) for route redistribution into OSPF:
1. Assign the metric type in the AS-External LSA.
The type is the method for influencing routing decisions for external routes.
2. Match the metric of the protocol route.
The metric value sets the priority for choosing this device for the route. The value none sets no
default, and 1 sets the highest priority for the route.
Exporting All Routes Except a Few Selected Routes
This method is a combination of
Exporting All Routes, page 149
). The basic steps to configure this method are outlined below:
1. Configure OSPF to export all routes of the protocol using the export command as described in
Exporting All Routes, page 149
.
2. Use route maps to configure routes to be denied by setting the action in the access list of the
route map to deny.
The configuration of the route map is similar to that described in the second method except that the
action is set to deny.
OSPF Configuration Examples
Each of the configuration examples in this section are constructed using the following basic steps:
1. Configure IP interfaces—One IP interface is required for each desired network (range of IP
addresses) being assigned to an OSPF area on Alteon.
2. Optionally configure the router ID—The router ID is required only when configuring virtual links
on Alteon.
3. Enable OSPF on Alteon.
4. Define the OSPF areas.
5. Configure OSPF interface parameters—IP interfaces are used for attaching networks to the
various areas.
