Route Redistribution Between OSPF and EIGRP (2024)

This is a Route Redistribution between OSPF and EIGRP configuration Lab. In this tutorial we will learn how to configure Route Redistribution between OSPF and EIGRP using Cisco Packet Tracer.I have made a step wise tutorial showing redistribution process between EIGRP and OSPF and also performed Network connection Testing after Configuration.If you are preparing for CCNP Certification this lab will help you score and learn Route distribution Questions.

Redistribution is done to enable communication between routers running different protocols.

For Example here in this lab you can see two different protocols EIGRP and OSPF.

Step 1: Assign IP Address on Each Router Interfaces First.

Step 2:Configure EIGRP on Router R1:

r1>enabler1#config tEnter configuration commands, one per line. End with CNTL/Z.r1(config)#router eigrp 100r1(config-router)#network 1.0.0.0r1(config-router)#network 3.0.0.0r1(config-router)#exitr1(config)#do writeBuilding configuration...[OK]r1(config)#

Step 3: Configure EIGRP and OSPF on Router R2:

r2>enabler2#config tEnter configuration commands, one per line. End with CNTL/Z.r2(config)#router eigrp 100r2(config-router)#network 3.0.0.0

r2(config-router)#exitr2(config)#router ospf 100r2(config-router)#network 4.0.0.0 0.255.255.255 area 0r2(config-router)#exitr2(config)#do writeBuilding configuration...[OK]r2(config)#

Step 4: Configure OSPF Routing Protocol on Router R3:

r3>enabler3#config tEnter configuration commands, one per line. End with CNTL/Z.r3(config)#router ospf 100r3(config-router)#network 4.0.0.0 0.255.255.255 area 0r3(config-router)#network 5.0.0.0 0.255.255.255 area 0r3(config-router)#exit

Step 5: redistribute EIGRP routes into OSPF.

r2(config)#router eigrp 100r2(config-router)#redistribute ospf 100 metric 1000 100 255 1 1500r2(config-router)#

Step 6: redistribute OSPF routes into EIGRP.

r2(config)#router ospf 100r2(config-router)#redistribute eigrp 100 metric 1 subnets

Step 7: Test routing Connectivity from PC.

Step 8:Check routing Table
