Configuring Advanced Routing Policies
8. Create the Export-Policy redistributing all (RIP, Direct) routes and the aggregate route
140.1.0.0/16 into RIP.
Example 2: Exporting to OSPF
It is not possible to create OSPF intra- or inter-area routes by exporting routes from the XP routing
table into OSPF. It is only possible to export from the XP routing table into OSPF ASE routes. It is
also not possible to control the propagation of OSPF routes within the OSPF protocol.
There are two types of OSPF ASE routes: type 1 and type 2. The default type is specified by the
ospf set ase-defaults type 1/2 command. This may be overridden by a specification in the ip-
router policy create ospf-export-destination command.
OSPF ASE routes also have the provision to carry a tag. This is an arbitrary 32-bit number that can
be used on OSPF routers to filter routing information. The default tag is specified by the ospf set
ase-defaults tag command. This may be overridden by a tag specified with the ip-router policy
create ospf-export-destination command.
Interface routes are not automatically exported into OSPF. They have to be explicitly done.
For all examples in this section, refer to the configuration shown in Figure 22 on page 260.
The following configuration commands for router R1:
• Determine the IP address for each interface
• Specify the static routes configured on the router
• Determine its OSPF configuration
