I came across a "feature" in Dialer watch today...
R1(Spoke)---------R2(Hub)
R1 uses ISDN as backup for its main link to the Hub site. Backup is configured using dialer-watch and it works very well.
R1 watches a route, and brings up the ISDN when the route disappears. So far so good.
However, if I reboot R1, and the main link to the hub fails at the same time, dialer watch never brings up the ISDN link once the router finishes its boot sequence. The reason for this (I guess) is that when the router reboots, it is watching a route which has never existed (as far as the router knows). Therefore dialer watch does not bother to bring up the backup link.
Some of you may think that the chances of this scenario occurring is quite slim. However, it did happen to me this morning! It is also quite conceivable that someone may decide to "reboot" the router is an effort to restore the main link...... If they do this, then bye bye backup.....
Has anyone come across this before? Is there a workaround? Can I turn this feature off? (but still use dailer watch).
Daniel
