Berkowitz: Building Service Provider Networks (Wiley) Greene and Smith: Cisco ISP Essentials (Cisco Press) Having given those references, ISIS is more common than OSPF as an ISP IGP. I have seen good designs with OSPF, generally where there were lots of servers in the ISP or there were other needs for finer-grained route propagation than is typical in ISIS. To clarify something in another post, however, an ISP needs _both_ an IGP and BGP. Many larger ones will also use (G)MPLS setup.
