I think there are a couple of scenarios for this problem. The one I have
been working on today is as follows
Area 0 --- R1 --- Area 1 ---- R2 ------ Area 1 ----- R3 ----- Area 2 ----- R
4
[ [
[---------------------ISDN----------------------[
I have Virtual link from R3 to R1 across Area 1 and ip ospf demand-circuit
of R3 only. The way I got it to work was to put both end of the ISDN in Area
1. It works fine that way, but if you put them area 0 the Isdn just stays up
all the time. If you put the ends in different area it gets really confused.
I'm going to try it now with the Isdn in another area, say Area 3 and see
what that does. I suspect this is the one where you need multiple virtual
links.

Subject: ospf demand circuits and virtual-links
There has been some talk about the demand-circuit command
not repressing
ospf hellos when configured in a virtual-link circuit. Can
anyone verify this?
Also, if so, under what circumstance and what is the remedy?
Thanks,
Curtis
