ISDN backup Config Template

Hi,

Our clients are connected to a 3640 Router. We have created dialers for each and every client but I still find that clients fail to auth or they cannot dial in.

Could someone tell me where I can find a template config that I can use to create a correct / proper ISDN backup config to place on both the client as well as my router?

Clients are using 1721s',2600s' and 2800s'

Thanks

Re: ISDN backup Config Template

Backup, means each client have two link, one primary and ISDN is a backup? One way to do this is floating static route, the configuration is the same for all routers.

Re: ISDN backup Config Template

Re: ISDN backup Config Template

Will try and do that a bit later. Don't want to do any testing during working hours.

Does the config I pasted not help you?
