In your example the answer would be yes. As you said the dialer watch
group can contain multiple routes. The router checks those routes and as
long as one of them is still active and points to a different interface then
the backup interface, the backup interface will not kickin. You can however
watch multiple routes that are all learned via one interface such that if
that interface or line goes down and there are no other paths to learn the
routes from, the backup interface will kick in.

Subject: Dialer watch question
Im reading a sample config for dialer watch:
http://www.cisco.com/warp/public/129/bri-backup-map-watch.html#dialerwatchop
e
ration
and it says:
"
a.. When a watched route is deleted, dialer watch checks for at least one
valid route for any of the IP addresses or networks being watched.
a.. If there is no valid route, the primary line is considered down and
unusable.
a.. Dialer watch then initiates the call, and the routers connect and
exchange routing information. All traffic for the remote network will now
use
the backup link.
b.. If there is a valid route for at least one of the watched IP networks
defined and the route is pointing to an interface other than the backup
interface configured for dialer watch, the primary link is considered up and
dialer watch does not initiate the backup link.
"
So does that mean if I configure:
dialer watch-list 1 ip 10.10.10.0 255.255.255.0
dialer watch-list 1 ip 20.20.20.0 255.255.255.0
int bri0
dialer watch-group 1
Then if route 10.10.10.0/24 goes down but 20.20.20.0/24 stays up, then
dialer
watch will NOT activate?
Thanks for your time,
Joe
