WAN scenario help needed

[hasnain321]

Hi all,

I have setup a network shown in the diagram. I am getting same routes via two different Clouds. What I want is to use one path as a preferred path over the other. I want to use BGP as routing protocol. I have control over both sides of the WAN link and I want this shifting to automatic on both sides of the link. Traffic should be symmetric.

Should I use IBGP between routers A,B and C and make route selection on router C or any other approach.

If one site is down via Could_1 it should be sending and receiving traffic via could_2 from all the sites and vice versa.

Thanks for your time

What are the "clouds" ?

BGP alone generally is not apt at it cannot be used for internal routing.

Thanks for reply.

Well clouds you can think of being private internet. Actually these are MPLS coulds from two different providers.

I know BGP alone is not option I want to know how can acomplish this task which protocol should i be using as IGP.
