      use a network device that can understand one of the routing technologies, and pass it onto the second.

      Or change it so both companies are using the same routing technology

      (IS there actually more than one routing protocol in use any more ? :P)

        The scenario will be,, Company A is using EIGRP in its network for routing and Company B is using OSPF in its network for routing. Now company A has merged to company B. I want to connect the 2 companies who are far away. How is it possible ?????????????

          You can redistribute eigrp into ospf and vice versa if needed. Just peer with the company via their chosen protocol and then redistribute between the two. Shouldnt have any issues with route feedback as long as the redistribution is being done on one router. If there are several routers then you need to consider route feedback and some filtering etc.


          Also Eigrp isnt really a plug and play protocol so I suggest you do some research on it, and OSPF is a very robust protocol as well.

              Yeah I was thinking the same thing. Regardless you need to understand what happens when you do redistribute between protocols. You should know what routes you are going to get on both sides even before redistribution is done. Just configuring it and hoping for the best can lead to problems.
