3. © 2009 Cisco Systems, Inc. All rights reserved. ROUTE v1.0—4-3 Lab Review: What Did You Accomplish?  Task 1: Implementing RIP, EIGRP, and OSPF Routing –What steps did you take to configure the RIPv2, OSPF, and EIGRP routing protocols?  Task 2: Implementing RIP Redistribution –What steps did you take to redistribute loopback interfaces into RIP and to redistribute RIP routes into EIGRP? –Have you also configured a static route on router R3 to establish connectivity in the opposite direction?  Task 2—Implementing OSPF Two Way Redistribution –What steps did you take to redistribute from OSPF to EIGRP? –What steps did you take to redistribute from OSPF to RIP?

4. © 2009 Cisco Systems, Inc. All rights reserved. ROUTE v1.0—4-4 Verification  Did you have enough information to create an implementation plan?  Did you successfully configure the RIPv2, EIGRP, and OSPF routing protocols such that all of the routes are present in the IP routing table?  Did you successfully configure redistribution into the RIP routing protocol and verify the presence of the requested route?  Did you successfully configure redistribution of RIP into the EIGRP routing protocol and verify the presence of the requested route?  Did you successfully configure redistribution from OSPF into RIP and from OSPF into EIGRP?

5. © 2009 Cisco Systems, Inc. All rights reserved. ROUTE v1.0—4-5 Checkpoints  Configure the RIPv2, EIGRP, and OSPF routing protocols.  Examine and verify that the routing protocols are up and routes exist inside the IP routing table.  Configure redistribution into RIP.  Configure redistribution from RIP into EIGRP.  Verify the RIP database and IP routing table.  Configure two-way redistribution from OSPF into EIGRP.  Verify an EIGRP topology and OSPF database.  Configure two-way redistribution from OSPF into RIP.  Verify the OSPF and RIP databases and IP routing table.

6. © 2009 Cisco Systems, Inc. All rights reserved. ROUTE v1.0—4-6 Sample Solution  RIPv2, OSPF, and EIGRP are configured on the routers.  Redistribution takes place into RIP and from RIP to EIGRP.  Static routes are configured.  Two-way redistribution is configured from OSPF into EIGRP and from OSPF into RIP.

7. © 2009 Cisco Systems, Inc. All rights reserved. ROUTE v1.0—4-7 Alternative Solutions  Different routing protocols can be used.  Static routes can be used.  Different path control tools can be used to manipulate the redistribution.  Redistribution can be configured by changing administrative distances and metrics.

8. © 2009 Cisco Systems, Inc. All rights reserved. ROUTE v1.0—4-8 Q and A  Why is routing protocol selection important?  Why is changing the administrative distance and metric important?  What must be used when configuring two-way redistribution?  Why are path control tools important?

9. © 2009 Cisco Systems, Inc. All rights reserved. ROUTE v1.0—4-9 Summary  Configure the RIPv2, EIGRP, and OSPF routing protocol to establish reachability in the network and enable destination-based forwarding.  Configure redistribution into the RIP protocol and from RIP to EIGRP to maintain the optimum path across the network.  Configure two-way redistribution of OSPF into EIGRP and OSPF into the RIP routing protocol, where the last example path control or route filtering must be used.
