BGP with two routers, one ISP

Hi Guys,

I have two CCR routers with separate connections to my ISP. BGP has been configured at the end.

What sort of configuration do I need to do at my end to ensure that this all works? Only one switch is being used, so both routers are connected to this.

It should be configured in an active/passive setup (prevent router failure at either my isp end, or mine).
