I disagree with your remark that "this is not an appropriate channel for this query". I would believe that Jean's query falls under the "open exchange of technical information" category.

Sorry, this is not a general help list for basic networking skills. There are many options for appropriate training available, but this is not an appropriate channel for this query.

Subject: Best way to have redundancy announcing on separate routers

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,
