Guys,
No, the idea is to have no routing protocol configured on the ISDN link. No
ospf/rip/igrp/eigrp.
As Aaron, was saying, all the normal ISDN configuration options will not
really work as you still need to have either some or other static route or
routing protocol configured.
I was wondering about configuring the ISDN as a bridged interface, or using
IRB. When using bridging you could also use the backup interface I assume ?
Has anyone tried this ?

When you state no routing protocol on the WAN. Do you mean you do not want
hellos keeping the ISDN link up?
If this is the case ospf supports on-demand circuits (only configure on 1
end).
You have to have some kind of route to the destination. Be it static or
dynamic! The router will buid a dynamic route on an unnumbered link but it
will be host based so you cannot rely on this.

Gentleman,
My network layout :
ISDN
----------
| |
-e0--RA--HDLC--RB--e0
OSPF OSFP
When HDLC link fails - enable ISDN as backup, BUT ....
No static routes and no routing protocol on ISDN
Can this be done ? If so how ?
I would like your input on this !
Ken
