use an extended access-list that denies "icmp any any" on top of the other
interesting traffic you'll have ... ensure of course that this line is
before the "permit ip any any"

Subject: RE: ISDN Backup without the backup interface command?
I'm familiar with using ip ospf demand circuit, but I have a question. Is
there a way to prevent the line to come up via a ping. In other words, I
only want the isdn line to come up ONLY if the frame relay goes down. I
don't want it to come up for any other interesting traffic and I don't want
to use backup command. What access-list can I use?

That's no trick, use ospf demand circuit
