I've never configured this but I thought I'd take a stab at it anyway.
My thinking is this: since IPX is not being routed directly across the
ISDN link, then there is no need to place IPX traffic in the dialer
list. You don't want IPX traffic to trigger the dialer, you want
IP-tunneled IPX traffic to trigger it. So, configure the dialer list so
that the IP tunnel itself is interesting and then utilize floating
static routes or dialer watch to bring up the backup line. If the main
line goes down, the router will still want to tunnel that traffic but it
then knows it has to bring up the backup link to reach the opposite end
of the tunnel.

I'm working on a situation where two routers are to be connected by a
frame-relay connection. An ISDN dial-backup will be available. A
tunnel
interface has been created to bring IPX across the IP Backbone. My
question
involves the dialer-list on the BRI interface.
When I'm defining interesting traffic for the list is the IPX traffic
to be
considered as interesting, or does the check for interesting traffic
occur
only after the IPX traffic has been encapsulated for use in the tunnel
and
thus, it is only IP traffic that should be examined? If the IPX traffic
is
to be looked at to define interesting traffic can more than one
dialer-group
be applied to the BRI interface in the same way that an interface can
have
more than one access-list as long as it's one per protocol, per
direction?
This way interesting IP or IPX traffic would bring up the backup ISDN
line.
