http://en.wikipedia.org/wiki/BGP http://en.wikipedia.org/wiki/Quagga_%28software%29 http://en.wikipedia.org/wiki/Provider-independent_address_space I'd start with those, so you understand how you can solve your requirement of managing a single range of IP addresses across two uplinks managed by different ISPs. Once you've got that down, start worrying about Pacemaker.
