[cisco-nas] question regarding TRACK PPPoE/cellular failover

[Steger, Christian]

hi!

thanks for your response, unfortunately "ip sla" is not a solution.
actually i wanna do 
something like that:

if a route or if a device on dialer1 is reachable "clear the cellular
interface" or something else..
just remember i would like to have a persistant connection on both
dialer interfaces (PPPoE as well as Cell)

* What if you track something over your PPPoE with IP SLA?

* 
* hi there!
* 
* 
* i am right now testing an failover enviroment between PPPoE and an
* Cellular
* interface.
* 
* i can realice it with 2 different dialers (dialer 1 PPPoE speaking
* PPPoE on
* FastEthernet) and the dialer2 which is bound to the cell interface. i
* solved
* the failover right now via route tracking, which works fine.. means
* when the
* primary interface fails the state is down and the cell interface
* (dialer2)
* is dialing in. - the problem is the fallback to the primary interface.
* in
* fact of dialer pesistant definition there seem not a really easy way
to
* "force the cell interface to disconnect".
* i have tried the backup interface statement, but my fastethernet will
* never
* go down except my dsl modem have a problem.
* 
* so any idea how to force the switching from cellular back to PPPoE?
