Cabletron Systems SmartSwitch Create a Direct export source, Exporting Aggregate-Routes into RIP

Chapter 11: Routing Policy Configuration Guide

Exporting All Static Routes Reachable Over a Given Interface to a Specific RIP- Interface

In this case, router R1 would export/redistribute all static routes accessible through its interface 130.1.1.1 to its RIP-interface 140.1.1.1 only.

1.Create a RIP export destination for interface with address 140.1.1.1, since we intend 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 17 on page 183, 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.
