ISIS is not an RFC, it's a protocol created by OSI (or ISO or whatever language
their acronym is in). Unless somebody subsequently created an RFC for it, it
is not under the IETF's realm. Although ISIS is a nice protocol, it wasn't
designed specifically with IP in mind. Though ISIS works well, OSPF is also a
clean protocol, and I believe that RFCs are much easier to obtain than OSI
specs. Though some ISPs use ISIS because there was a gap for a good IGP until
OSPF came along (RIP being the only alternative). Few places implement new
ISIS networks anymore.
Somebody please correct me if I'm wrong.
As overated as MPLS is, I'd rather see it than ISIS come first.
