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

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.......
