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>enable r1#config t Enter configuration commands, one per line. End with CNTL/Z. r1(config)#router eigrp 100 r1(config-router)#network 1.0.0.0 r1(config-router)#network 3.0.0.0 r1(config-router)#exit r1(config)#do write Building configuration... [OK] r1(config)#
Step 3: Configure EIGRP and OSPF on Router R2:
r2>enable r2#config t Enter configuration commands, one per line. End with CNTL/Z. r2(config)#router eigrp 100 r2(config-router)#network 3.0.0.0
r2(config-router)#exit r2(config)#router ospf 100 r2(config-router)#network 4.0.0.0 0.255.255.255 area 0 r2(config-router)#exit r2(config)#do write Building configuration... [OK] r2(config)#
Step 4: Configure OSPF Routing Protocol on Router R3:
r3>enable r3#config t Enter configuration commands, one per line. End with CNTL/Z. r3(config)#router ospf 100 r3(config-router)#network 4.0.0.0 0.255.255.255 area 0 r3(config-router)#network 5.0.0.0 0.255.255.255 area 0 r3(config-router)#exit
Step 5: redistribute EIGRP routes into OSPF.
r2(config)#router eigrp 100 r2(config-router)#redistribute ospf 100 metric 1000 100 255 1 1500 r2(config-router)#
Step 6: redistribute OSPF routes into EIGRP.
r2(config)#router ospf 100 r2(config-router)#redistribute eigrp 100 metric 1 subnets
Step 7: Test routing Connectivity from PC.
PC>ipconfig FastEthernet0 Connection:(default port) Link-local IPv6 Address.........: FE80::20A:41FF:FE75:7366 IP Address......................: 1.0.0.2 Subnet Mask.....................: 255.0.0.0 Default Gateway.................: 1.0.0.1
PC>ping 5.0.0.2 Pinging 5.0.0.2 with 32 bytes of data: Request timed out. Reply from 5.0.0.2: bytes=32 time=0ms TTL=125 Reply from 5.0.0.2: bytes=32 time=0ms TTL=125 Reply from 5.0.0.2: bytes=32 time=0ms TTL=125 Ping statistics for 5.0.0.2: Packets: Sent = 4, Received = 3, Lost = 1 (25% loss), Approximate round trip times in milli-seconds: Minimum = 0ms, Maximum = 0ms, Average = 0ms PC>
Step 8:Check routing Table
