With respect to these OSPF questions, how many people are running two OSPF processes on each router (v4 and v6) to support dual stack rather than migrating (or just enjoying their existing) ISIS (OSI) implementations?
You left out the option of using ospf3 to do both v4 and v6. Works on juniper and foundry at least.

Thank you. Apparently Cisco supports it (or something like it) too.
Seems silly to migrate your existing OSPFv2 to an extra instance of OSPFv3, leaving 2 separate OSPFv3 instances. Why not just stick with your existing OSPFv2 and add OSPFv3 for IPv6? Or if you want to migrate your IPv4 IGP, go directly to IS-IS so you can have a single link-state database, single process, etc. for both IPv4 and IPv6.
