Best way to have redundancy announcing on separate routers

[Jean Franco <jfranco () maila inf br>]

Hi Folks,

I'm trying to achieve total redundancy on a multihomed environment:

ISP 1 <=> Router 1 <= X => Router 2 <=> ISP 2
Where X is my Network.

In the example below, he announces separate blocks to each ISP.

I would like to do a failover model, where if one ISP goes down the other
would take over.
Please share your thoughts on this.

Best regards,
