Network World April 9, 1990 (page 59):
"There is no practical limit to the number of interconnected networks OSPF =
and Dual Intermediate System-to-Intermediate System can support"...
"From the onset, OSPF was intended to be short-term, for IP-only"..
"Dual routing is intended to be more of a long-term solution because there =
will be very few pure OSI or TCP/IP routing environments in the future."

Technology prognosticators shouldn't try their hands in Vegas. Just saying.
With respect to these OSPF questions, how many people are running two OSPF =
processes on each router (v4 and v6) to support dual stack rather than migr=
ating (or just enjoying their existing) ISIS (OSI) implementations?
