[c-nsp] dialer watch vs. matching interesting traffic

[Piestaga]

It changes my point of view.
I have found many examples of configurations on cco that were putting
"access-list" for indication of an "interesting traffis" and those
docs were source of my questions.

I agree with you, that it does not make sense in this case but I
though that this is an additional feature to dialer watch.
Now I know it is not :-)    Thanks.

Tell me if I am wrong.
-  dialer watch can be useful for CPE that are "equipped" with dynamic
 routing protocol and when we want to watch one particular adres or
 network,
 - floating static routing is necessary in all remaining configs
 expecially when on CPE router we rely only on default routing (just
phisical connection of CPE to the IP network)
