can you pu dial back up on Serial line PVC that has 2 DLCI's?
I have a remote site that has one cisco router with 1 CSU/DSU connecting to the S1 interface. On that I have two DLCI's that go to the Frame cloud. I have DDR backup dial interface, but it is married to the s1.1 interface. I want to use the dialbackup on the S1 interface so that when the whole circuit goes down, it will activate. Now when only one of the DLCI's goes down the dialback up activates. I have tried to move the dailbackup statement to the S1 interface with no luck.....thoughts guru's?
Here is a drawing and the config file....

no.....the DLCI's go to different parts of the country.
why dont you just use an ISDN backup
The point is to failover to a 3rd option only after the first two are in a down state.
If the circuits were terminating to the same router, a multilink interface with the failover would work -- which is what is needed, a single interface to handle both serial interfaces. I can't find any documentation that provides for a primary and secondary backup interface.

feya28, no help.
jesper...It is one physical interface with 2 sub interfaces "DLCI's" So the question remains:
How to put the backup on the S1 so that if both DLCI's go down, the dialback will kick in...

This solution is only available to members.

Have you looked at frame-relay multilink? You set the IP address on the multilink (ppp) interface at both ends and specify the dialer backup on that same interface.
I haven't tried it but, if you can do this, logically it should work.
