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—5-3
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?

ROUTE v1.0—5-4
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.

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.

ROUTE v1.0—5-6
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.

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?

ROUTE v1.0—5-8
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.
