I am building redundancy within that setup. I mean it will be software based BGP so if hardware if fried up, it will break BGP session and pull off routes anyway and for cases like DNS server (software) failure, I will monitor it via simple bash script which can turn bgp daemon down. So once it is off, routing tables should take it to different node.
