In the same vein, are folks finding ISPF stable in the field? Has anyone
enabled this on their ospf speaking boxen in a "large" network?

Also, if anyone has done some lab trials I'd be interested to know the
outcome. If folks haven't tested this (but could easily), perhaps they
could construct an almost-full-mesh of a dozen or so routers, ISPF
enabled on each, fill lsa db's with lots of type-2's, then script the
oscillation of links within the network. Hopefully it wouldn't fail
differently with ISPF disabled, but something tells me not to assume
anything. For some reason I have a unsettled feeling about features
added to Cisco OSPF post-Katz.
