Question on ISIS and IP Mismatches [7:64309]

2003-03-03 Thread CiscoNewbie
Hi all.  I am thinking of adding a few Cisco into my lab which consist of
mainly Juniper routers running ISIS.  A few months back I got caught up in a
nice troubleshooting issue with ISIS on these routers while working on a PTP
in that I had misconfigured an IP address on one side of an interface and a
different network IP on the other side of the PTP.  Being that ISIS does not
care about IP, the adjacencies forms anyways like they should have.  Now I
know that this is the nature of ISIS and not an issue with the router but
recently Juniper modified their JUNOS OS so that it checks for proper match
of IP parameters.  My question is, does Cisco have this built in behavior in
that it will check for this mismatch?  If so, what IOS code/train has it?

Thanks.

The last word on I saw on this issue was that the adjaceny would still form.
You could check into the release notes for the most recent releases, but
12.1 GD and before was still doing it.
