© 2009 Cisco Systems, Inc. All rights reserved. ROUTE v1.0—5-3 Lab Review: What Did You Accomplish?  Task 1: Implementing EIGRP Routing –What were the steps you took to configure EIGRP routing protocol?  Task 2: Implementing Policy-Based Routing (PBR) –Which tools did you use to configure PBR? –Where did you apply the PBR configuration for the traffic passing through the router? –Where did you apply the PBR configuration for the traffic locally originated in the router?

ROUTE v1.0—5-4 Verification  Did you have enough information to create the implementation plan?  Did you successfully configure the EIGRP routing protocol?  Did you check which path the packets took?  Did you successfully configure PBR?  Did the packets take the same path they took before PBR was applied?

© 2009 Cisco Systems, Inc. All rights reserved. ROUTE v1.0—5-5 Checkpoints  Configure EIGRP.  Examine and verify that the EIGRP routing protocol is up and running.  Verify the IP routing table.  Examine the path of IP packets.  Configure PBR.  Examine the path of the IP packets after the PBR configuration.

© 2009 Cisco Systems, Inc. All rights reserved. ROUTE v1.0—5-6 A Sample Solution  EIGRP is configured on all the routers.  EIGRP automatic summarization takes effect.  PBR is configured on routers R1 and R3 to manipulate the path selection.

© 2009 Cisco Systems, Inc. All rights reserved. ROUTE v1.0—5-7 Alternative Solutions  Another routing protocol can be used to provide a different path.  Static routes can be used.  The metric and administrative distance can be changed.  Another path control manipulation tool can be used.

ROUTE v1.0—5-8 Q and A  Why is routing protocol selection important?  Why is changing the default destination-based forwarding important?  Which tool is used for PBR implementation?  How is classification in the route map performed?  How is the path between the packet source and destination verified?

© 2009 Cisco Systems, Inc. All rights reserved. ROUTE v1.0—5-9 Summary  Configure an EIGRP routing protocol to establish reachability in the network and enable destination-based forwarding.  Configure policy-based routing to manipulate the path for a specific set of packets and verify the configuration.
