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. https://www.networkstraining.com/cisco-bgp-configuration-tutorial/ 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,
