When we decided to go dual-stack many many years
ago, we faced the choice of either running OSPFv2
and OSPFv3 in parallel in the core, or just running
IS-IS. Several of us on the team had experience
with IS-IS from previous jobs, so we decided to
shift over from OSPF to IS-IS to simplify the
environment by only needing a single IGP for
both address families.
Hope this helps answer your question.
Thanks!
Matt
