OSPF for IPv4 over IPv6 only?

everytime I post to this list I am learning so much - very interesting,
first time I actually read RFC 5838.

Very interesting. As far as I recollect, we did give babel a try way
before we introduced OSPF. I am not sure anymore what made us switch over
to OSPF, but vaguely recalling we had to quickly introduce an IGP due to
an architecture change, wanted to go with babel, we faced some issues
with the setup and continued with OSPF and settled on it.

But from a simplicity point of view, babel is indeed very attractive and
it made it back on my "to recheck in the future"-list.

In a way it's great to see you have had the same issue, seeing we are on
a similar path for network designs.

Cheers,

Nico
