Redistribution lab for CCNP Route Exam


Redistribution of  OSPF and EIGRP lab

  

     For some reason I saw this exercise in several web sites and I couldn't make it work .I knew something was wrong..I found out that a lot of people were missing vital pieces of information.So, so far, this would be ,till now ,the only working exercise properly and fully  configured.. !

In this topology we have 4 routers., R1, R2 and R3 are running in EIGRP AS 100. While R2’s s0/2 is running in OSPF area 24, R3’s f0/0 interface is running in OSPF area 34.
 We will redistribute OSPF into EIGRP so that they can communicate with each other.Finally you will ping from R1 to Test IP 172.16.100.1 must be successful.

We will do this in 3 process:
  1. Configuration of terminals of each router
  2. Redistribution
  3. Verification and testing

2. Configuration for the exam



Go to R2 and do a show int s0/2


In delay .. instead of doing a 20000  we will use 2000  ( divided by 10)

R2#config terminal
R2(config)# router ospf 1
R2(config-router)# redistribute eigrp 100 metric-type 1 subnets
R2(config-router)#exit
R2(config-router)#router eigrp 100
R2(config-router)#redistribute ospf 1 metric 1544 2000 255 1 1500


We will do something similar in R3 , , the F0/0 terminal

 

 


R3#config terminal
R3(config)#router ospf 1
R3(config-router)#redistribute eigrp 100 metric-type 1 subnets
R3(config)#exit
R3(config-router)#router eigrp 100
R3(config-router)#redistribute ospf 1 metric 100000 100 255 1 1500



In delay we will add a "0" in this scenario



Now, we dont need to do this but it's good to check the configuration

We  see in the past shot that it learns about 192.168.2.2 via s0/1  with the commands show ip route and show ip int brief

You have a well configured exercise..!No doubts for the test!

 Verification & testing of R1:
 
Show ip route on R1: You will see the all other routes if you done the correct configuration also ping from R1 to 172.16.100.1 should be successful.







Your exercise is done!
