Any experience with OSPFv3 for IPv4?

RFC5838, Support of Address Families in OSPFv3, defines how OSPFv3
can support IPv4 as well as IPv6.

Does anybody have practical experience with this?

If so, is it something to recommend?

We have always used ospfv3 for v6 and traditional ospf for v4 in parallel. The reason at the time was not all software releases did v3. The core of the network ran isis but not isis-mt as that was still emerging. This was ... Uh thinking now, about a decade ago.

Certainly. JunOS has supported it for quite a while:

"By default, OSPFv3 supports only unicast IPv6 routes. In Junos OS
Release 9.2 and later, you can configure OSPFv3 to support multiple
address families, including IPv4 unicast, IPv4 multicast, and IPv6
multicast."

Just to clear the dead air...

I am using OSFPv2 for IPv4 uni and OSPFv3 for IPv6 uni.

I have found that all implementations which I have seen/been a part of/consulted for/advised, if using OSPF for their IGP in any way, do this.

On top of that, in most cases, this is in combination with iBGP.. e.g. Loopbacks and connecteds in OSPF(v2/3-4/6) and iBGP loop to loop full mesh + RRs. This is the common and best of both worlds that I see.

While I know this is not the answer to your question, I imagine you are going to see a bunch of +1s and a few 'why not use ISIS's which may essentially answer the question as "no". :)

Cheers,
Aaron

If I interpret this correctly,

I'd say that JunOS is a working implementation. I've never tried, though.

Note that I'm still running JunOS 9.6R2.11, quite an old version.
