Notably, support for OSPF is somewhat common on "layer 3 switch" 
products while IS-IS support is significantly less common.

Most "router" products seem to support either.

I was of the impression that there was a draft or similar for 
single-topology (IPv4+IPv6) OSPF.  Did anything ever come of that?
