RE: dialer-group under BRI interfaceyes, this is correct.
you could just as easilty said
dialer-list 1 pro ip deny
or even easier, do not define a dialer-g under the interface and there-for
it will not call a dialer-list, thus making all traffic "uninteresting", not
just ip traffic so you're covered on all bases............like if for some
reason you had dlsw peering on the loopbacks of the isdn routers (which also
have a frame realy connection to each other), there would be no chance that
dlsw could chose to bring up the idsn link if for some reason the cost of the
link was "less" than that of the frame-relay connection.
see....when i comes to "cisco" questions, you have to think about granularity
and "the big picture". ask youself "could anything else bring up the link
besides IP?"..... :) i know this is beyond the scope of your
question, but certianly something to think about.

Ok, I think I understand what you are saying, John. The dialer string will
just initiate the call to the remote location. On the issue of keeping the
call up...we have to look at what you're dialer list looks like. Try
this....
under the interface.....
dialer-group 1
global config mode....
dialer-list 1 protocol ip permit
My understanding of this is....if the "interesting" traffic does not match
what you are sending....then, this line will drop after the dialer
idle-timeout expires, which I believe is 120 by default. So, if your dialer
list only matches tftp traffic and you are doing a ping to keep the line
up...then the line will drop after idle-timeout expires (if, ICMP is not
interesting traffic). Please correct me if I am wrong on any of this.

dave,
i use the omission of the dialer-group because i have never been able to
keep layer-2 up by removing the dialer-string from the router i wanted
to
prevent from dialing. if i remove the dialer-string then i could not
ping
from the other side to bring the link up, but as soon as i put the
string
back then layer 2 comes back up.......
