Adding second MPLS carrier for backup - what is best approach

[mpls-experts1]

I have an MPLS network with carrier 1. I am about to install a second MPLS network with carrier 2. Can any direct me on the best approach to configure the routers so that a failure from carrier 1 seamlessly will redirect traffic via carrier 2. And then switch back after carrier 1 is working properly? Are there any FAQs on this subject? Using Cisco 1841, 2811 and 2490 routers.

you should go with the MP-eBGP. With this your purpose will be solved.

Have you explored using BGP to redirect traffic if the primary network path is unavailable?
