Karim,
For the first scenario - I would use two floating static and dialer-map
statements.
For the second scenario, I would use dialer-watch. Dialer-watch will
not kick in until ALL "watched" routes are lost - so it would not work
for your first scenario.
From Cisco IOS Dial Technologies Configuration Guide, Release 12.3:
"Monitoring the watched routes is done in the following sequence:
1. Whenever a watched route is deleted, Dialer Watch checks whether
there is at least one valid route for any of the defined watched IP
addresses.
2. If no valid route exists, the primary line is considered down and
unusable.
3. If a valid route exists for at least one of the defined IP addresses
and if the route is pointing to an interface other than the backup
interface configured for Dialer Watch, the primary link is considered
up.
4. If the primary link goes down, Dialer Watch is immediately notified
by the routing protocol and the secondary link is brought up.
5. Once the secondary link is up, at the expiration of each idle
timeout, the primary link is rechecked.
6. If the primary link remains down, the idle timer is indefinitely
reset.
7. If the primary link is up, the secondary backup link is disconnected.
Additionally, you can set a disable timer to create a delay for the
secondary link to disconnect, after the primary link is reestablished. "
HTH,
JDC

Subject: Watch-list question....
Hi all,
Would like to know the difference between the following 2 scenarios:
- When asked to initiate a call when losing reachability to any of 2
given routes to watch.
I believe that I need to create 2 dialer-maps statement (if using legacy
DDR) plus dialer watch-group (in either legacy or dailer interfaces).
Whenever the reachability lost to any of the two routes, a call will be
initiated.
- I asked not to initiate a call only if reachability lost to both
routes, what will be the solution ????
Regards,
Karim.
