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?

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?

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.

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.

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.

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?

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.
