[c-nsp] ISDN backup for multiple Internet customers

[Vincent De Keyzer]

Hello,

 

we are a small ISP.  We currently have a ISDN access router that is used by
one customer only. It works with dialer-watch on the CPE: if OSPF adjacency
goes down on the CPE, the CPE dials and forms an adjacency with the access
router over the ISDN link.

 

Now a second customer wants the same service. I would like to use the same
ISDN access router for both customers. Can somebody please point me to a
document describing how to do this?

 

Thanks in advance,

 

Vincent
