Chapter 16: Configuring Routing Policies on the SSR
• Export destinations and export sources, which you will include in your export policies.
A destination can be a particular interface or gateway. A source can be a particular
interface, gateway, autonomous system, or aggregate route.
• Import sources that you will include in your import policies.
• Filters, which are used to match a certain set of routes by destination or by destination
and mask.
• Aggregate destinations and aggregate sources for aggregate routes.
• Optional Path Attribute Lists to include with your export destinations and BGP input
sources.
Export Destination Building Blocks
An SSR’s export routing policy can include multiple export destination building blocks
that specify an export destination for RIP, OSPF, or BGP routes. Each routing policy can
include export destinations for RIP, OSPF, BGP or any combination of the three.
You can use Configuration Expert to create RIP, OSPF, and BGP export destination
building blocks. The method you use to define these building blocks depends on which
protocol the building block is for. Separate discussions on defining RIP, OSPF, and BGP
export destination building blocks follow.
Configuring and Modifying RIP Export Destinations
A RIP export destination building block specifies an export destination for RIP routes.
To define RIP export destination building blocks:
1. Start Configuration Expert if you have not already done so.
2. Open the configuration file you want to modify and then double-click that file’s
Routing Configuration object.
3. Double-click the IP Routing Configuration object.
4. Double-click the IP Unicast Routing object.
5. Double-click the Routing Policy Configuration object.
6. Double-click the Building Blocks object.
7. Double-click the Export Destination object.
8. Double-click the RIP object, and then do one of the following:
– If you are creating a new export destination, click the Configure New RIP Export
Destination object.
– If you are modifying an existing export destination, select that export destination.
