Chapter 6: Routing Policy Configuration Guide
SSR User Reference Manual 6 - 31
ip-router aggr-gen destination aggrDst140 source allAggrSrc network 140.1.2.0/
24
4. Create a RIP export destination for interface with address 130.1.1.1, since we in-
tend to change the rip export policy only for interface 130.1.1.1.
ip-router policy create rip-export-destination ripExpDst130 interface
130.1.1.1
5. Create a Aggregate export source since we would to export/redistribute an aggre-
gate/summarized route.
ip-router policy create aggr-export-source aggrExpSrc
6. Create a RIP export source since we would like to export RIP routes.
ip-router policy create rip-export-source ripExpSrc
7. Create a Direct export source since we would like to export Direct routes.
ip-router policy create direct-export-source directExpSrc
8. Create the Export-Policy redistributing all (RIP, Direct) routes and the aggregate
route 140.1.0.0/16 into RIP.
ip-router policy export destination ripExpDst130 source aggrExpSrc network
140.1.0.0/16
ip-router policy export destination ripExpDst130 source ripExpSrc network all
ip-router policy export destination ripExpDst130 source directExpSrc network
all
Example 2: Exporting to OSPF
It is not possible to create OSPF intra- or inter-area routes by exporting routes from the
SSR routing table into OSPF. It is only possible to export from the SSR 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.
