As I mentioned in a previous post, it's been possible to run OSPFv2 at the interface level for years now. It'd be my recommendation. In IOS, however, "passive-interface" works differently from IS-IS. From my experience (well, 12.0S on the XR 12000 anyway), "passive-interface" for a Loopback interface doesn't work unless you either run OSPF on the Loopback interface or add the Loopback's IP address as a "network" statement. I find this really odd, and our Cisco SE says that's how it's supposed to work. IS-IS on IOS, on the other hand, works as expected - "passive-interface" introduces whatever subnet is on an interface into the IS-IS LSDB, but does not run IS-IS on that interface. Interestingly, OSPF works like this on Junos (which seems natural). So not sure whether this issue is specific to IOS. At any rate, I'm an IS-IS house so don't really have much interest in digging deeper into this.
