Could someone please clarify the different ways of having backup dialers for
the various protocols.

>From my understanding, you can use (please let me know if there are others):
        * Backup command
        * Floating static route (static route with admin distance greater than
the
IGP's admin distance)
        * Dialer Watch

However, from what I know OSPF can have it's interface cost manipulated so
the dialer interface will remain the backup because of it's higher cost. I
believe the command is "ip ospf cost XX".

I also know that the bandwidth of the interface can be manipulated so that
OSPF cost of the interface can also be manipulated that way.

So would I be able to manipulate the bandwidth parameters for EIGRP and IGRP
for it to calculate a lower cost for the dialers, in order for it to be a
backup interface since there is no command to manipulate cost on an
interface for EIGRP/IGRP?

Thanks

Albert
