Chapter 6: Routing Policy Configuration Guide
6 - 30 SSR User Reference Manual
1. Create a RIP export destination for interface with address 140.1.1.1, since we in-
tend to change the rip export policy for interface 140.1.1.1
ip-router policy create rip-export-destination ripExpDst141 interface
140.1.1.1
2. Create a Static export source since we would like to export static routes.
ip-router policy create static-export-source statExpSrc130
interface 130.1.1.1
3. Create a RIP export source since we would like to export RIP routes.
ip-router policy create rip-export-source ripExpSrc
4. Create a Direct export source.
ip-router policy create direct-export-source directExpSrc
5. Create the Export-Policy, redistributing all static routes reachable over interface
130.1.1.1 and all (RIP, Direct) routes into RIP.
ip-router policy export destination ripExpDst141 source statExpSrc130 network
all
ip-router policy export destination ripExpDst141 source ripExpSrc network all
ip-router policy export destination ripExpDst141 source directExpSrc network
all
Exporting aggregate-routes into RIP.
In the configuration shown in Figure 2 on page 6 - 21, suppose you decide to run RIP
Version 1 on network 130.1.0.0/16, connecting routers R1 and R3. Router R1 desires
to announce the 140.1.1.0/24 and 140.1.2.0/24 networks to router R3. RIP Version 1
does not carry any information about subnet masks in its packets. Thus it would not be
possible to announce the subnets (140.1.1.0/24 and 140.1.2.0/24) into RIP Version 1
without aggregating them.
1. Create an Aggregate-Destination which represents the aggregate/summarized
route.
ip-router policy create aggr-gen-dest aggrDst140 network 140.1.0.0/16
2. Create an Aggregate-Source which qualifies the source of the routes contributing
to the aggregate. Since in this case, we do not care about the source of the contrib-
uting routes, we would specify the protocol as all.
ip-router policy create aggr-gen-source allAggrSrc protocol all
3. Create the aggregate/summarized route. This command binds the aggregated
route with the contributing routes.
ip-router aggr-gen destination aggrDst140 source allAggrSrc network 140.1.1.0/
