Wrong :
Dialer Watch provides the following advantages:
Routing protocol independent--Static routes or dynamic routing protocols,
such as Interior Gateway Routing Protocol (IGRP), Enhanced IGRP (EIGRP) or
Open Shortest Path First (OSPF) can be used.

Dialer watch is NOT for OSPF, it requires IGRP or EIGRP and it is only for
IP.
