How to configure Redistribution between EIGRP and RIP

In previous lessons I explained the basics of redistribution and I also showed you how to configure redistribution between OSPF and RIP. This time we’ll take a look at redistribution between EIGRP and RIP. Let’s take a look at the topology that we will use:

EIGRP RIP Redistribution R1 R2 R3

Above we have 3 routers. Router R1 and R2 are configured for EIGRP. R2 and R3 are both configured for RIP.

In previous lessons I explained the basics of redistribution and I also showed you how to configure redistribution between OSPF and RIP. This time we'll take a look at redistribution between EIGRP and RIP. Let's take a look at the topology that we will use: Above we have 3 routers. Router R1 and R2


First we will configure EIGRP and RIP without any redistribution:

R1(config)#router eigrp 12
R1(config-router)#no auto-summary 
R1(config-router)#network 1.1.1.0 0.0.0.255
R1(config-router)#network 192.168.12.0
R2(config)#router eigrp 12
R2(config-router)#no auto-summary 
R2(config-router)#network 192.168.12.0
R2(config)#router rip
R2(config-router)#no auto-summary 
R2(config-router)#version 2
R2(config-router)#network 192.168.23.0
R3(config)#router rip
R3(config-router)#version 2
R3(config-router)#no auto-summary
R3(config-router)#network 192.168.23.0
R3(config-router)#network 3.3.3.0

Above are the router configurations I’ve used, nothing special…redistribution doesn’t happen automatically this is something we have to do ourselves. Let’s configure it:

R2(config)#router eigrp 12
R2(config-router)#redistribute rip metric 1500 100 255 1 1500

I’m redistributing RIP into EIGRP and I have to specify the metrics. Pick whatever values you like. In you don’t specify the seed metric than the default one will be infinity and your redistributed routes don’t show up!

  1. Hey René,
    you missed something in the command syntax. After I have read your lesson, I tried the example. With the shown syntax John still doesn’t advertise the Loopback addresses and the connected network. You probably wrote it in the lesson, but I had to complete:

    John(config)#router eigrp 12
    John(config-router)#redistribute rip
    John(config-router)#redistribute connected
    
    John(config)#router rip
    John(config-router)#redistribute eigrp 12
    John(config-router)#redistribute connected
    

    With this syntax, John started to advertise the Loopback and his directly connec

  2. Hi Sascha,

    That’s right, this tutorial is just an overview of redistribution but I didn’t show the full config. Here’s the configuration example for those 3 routers:

  3. Hi Lazaros,
    When we do redistribution from Eigrp to OSPF vice versa, which exactly routes are advertised, the best routes in routing table it self OR all routes of EIGRP (or OSPF) before comparing the Admin Distance between different Protocols in routing table.?

  4. Lazaros,
    Many thanks for your usual support

  5. Hi Waleed,

    That would prevent routes from looping around but it also means you have a single point of failure. Redistribution on two routers is no problem but you have to understand and deal with potential issues. For example, take a look at route tagging:
