For giggles:

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 migrating (or just enjoying their existing) ISIS (OSI) implementations?
