If you do not want the ISDN link to be kept up indefinitely by IGRP updates,
and you do not configure static routes. How will the router know about any
routes via the ISDN incase of a frame relay failure? My point is, Yes
Bandwidth and Delay in a routing perspective will do fail over but if you
are not getting the updates there are no routes to fail over to, therefore
you have no "trigger" to dial the ISDN.

Subject: ISDN backup problem
-----------
Router A IGRP Router B
======
----- Frame-relay connection
==== ISDN connection
Router A and Router B connect by Frame-relay, and ISDN as backup link, the
IGRP over this two connection. If the FR connection down, I hope the ISDN
connection will bring up to backup the FR connection. Can I use the
"bandwidth" or "delay" cause the IGRP to select the FR connection, only use
the ISDN to be backup link( I know the floating static route, backup
interface, snapshot, dialer-watch can do that, is there any other solution?
)
Thanks,
Richard
