ISDN backup Config Template

bradlesliect · ‎02-25-2007

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

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.

bradlesliect ,

is it possible to post some console logs when dialin happens and debugs if possible.

bradlesliect · ‎02-26-2007

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?

yep!! Config seems to be ok ok.it hard to judge when router is not in our hand.

pls post log/debug / sho isdn stat cmds
