We have an ISDN link between 2 locations.
but when we tried to ping doesn't go thru
with each other...
Can please someone check if there7s a problem on the config??
We're not sure yet if it will work or not
if it happens that the main line is down.
Here's the config.i hope this is enough

I thought that I had already explained it. But let me try it again in a slightly different way. The router will only activate the ISDN when a packet matches the dialer list (which uses an access list to identify the traffic). Since there is no permit in the access list for a packet whose source address is the BRI, then a ping from the BRI to the other BRI does not match and the BRI will not activate. If you want to be able to test by ping from BRI to BRI then you need to add a statement in the access list to permit that host to host traffic.

Hi,
Please check the link below for more information on how to configure and ISDN link.

Let me know if it helps.

It would be helpful if we had more of the router config. The title of the post indicates ISDN back up and it would be helpful to know if the ISDN is configured as a backup interface for some primary interface or is configured with dialer watch for its activation, or is configured with floating static routes for its activation. If you provide more config detail we might understand the problem better and be able to give you a better suggestion.
If the ISDN is configured as a backup-interface for some primary interface then this may be normal behavior. The backup interface will be in standby state and will not make a call or answer a call unless there is a failure on the primary interface (and an interface shutdown will not start the backup interface). The output of show isdn status would help us see whether this is the issue or not.
I do see a couple of things in the config to comment about. I see ppp authentication chap on Site B but no ppp authentication on Site A. I believe that both sites need ppp authentication.
I see that Site B has ppp multilink but I do not see multilink on Site A. I believe that there should be consistency between the sites about this.
I see that Site B is configured with a dialer-group but that Site A is not. Dialer-group is essential to initiating a call. On that basis I have seen some people configured dialer-group on the router to initiate the call and not configure dialer-group on a router that they want to be an "answer only" (not initiate). But dialer-group is also important in resetting the inactivity timeout and avoiding dropping calls before it should. If a router does not have dialer-group it will never reset the inactivity timer and when that timer expires it will drop the call. A much better way to make a router be answer only is to not put a phone number into its dialer map.
The callback functionality can be difficult. If you remove the callback parts of the config on both sites (temporarily for testing purposes), does the router then be able to place the call?

Thanks for the additional information. I believe that it is helpful in better understanding what is going on in your situation. Here are some of the things that I see in it:
- I do not see any configuration of backup-interface so my question about possibly being in standby state is not the issue.
- Site A does have a floating static route for the LAN subnet of B pointing to the ISDN so if the primary route for the LAN at B (which I assume would be learned via BGP) is removed then A will use ISDN to try to get to B. It looks like this should work ok.
- As I mentioned before Site A does not have a dialer group configured so it is not able to initiate a connection to B. It can only answer when B attempts to initiate a connection. If this is what was intended, then this is not a problem - other than the fact that it will not reset the inactivity timer.
- There are several things in the config at B that puzzle me. There are 2 floating static routes on B which point to the ISDN to A. But neither of them is for the subnet at A. I am not clear why you are routing 192.168.52.0 and 192.168.56.0 to A but not routing the subnet at A.
- I believe that the dialer list at B is a problem. This is what allows B to initiate a call over the ISDN. The dialer list only allows 4 IP addresses as the source address (192.168.60.64, .65, .66, and .67) and only allows it to destinations in 192.168.52.0. If your attempt to test by using ping was sourced from one of the four addresses and if the destination of the ping was in 192.168.52.0 then it looks to me like the ISDN should have worked. And if the ping was not from that source and to that destination then the dialer list is the reason that ISDN did not work.
You know this environment and we do not. Perhaps it makes sense to you but to me it looks like a problem.

Hi Rick
Thank you for the attention.
I understand the dialgroup...if no packets from the host in the dialgroup, then the back will remain down...that's when the main link goes down.
What we're trying to initiate is to check if the back up works ok...and we tried it by ping test.
from site B, source will be the ip add of
site B's BRI port and destination is the Bri port of Site A.
The problem is the ping won't go thru..
That's what's questioning me...
what do you think???
Thank you very much
i really appreciate it...
07-03-2008 09:05 AM

I thought that I had already explained it. But let me try it again in a slightly different way. The router will only activate the ISDN when a packet matches the dialer list (which uses an access list to identify the traffic). Since there is no permit in the access list for a packet whose source address is the BRI, then a ping from the BRI to the other BRI does not match and the BRI will not activate. If you want to be able to test by ping from BRI to BRI then you need to add a statement in the access list to permit that host to host traffic.

I understand now....
I almost laugh when I checked the config again
and noticed that...
looks like I was just looking too far...
It was really helpful..
very kind of you...
again..thanks for the time...

Thanks

I see that access list 120 has a bunch of entries added including one that should allow ping from the BRI at B to the BRI at A. The dialer list was an issue before and I believe that it is not the issue now. If ping does not work then we need to look for something else.
I would like to start with the output of show isdn status from both routers. Can you post that?
Assuming that the status looks normal we need to look at some other things to determine why ping is not working. I will list several debugs that may show us the problem. For ease of interpretation I would suggest that you run then one at a time (start the first debug, attempt the ping, gather the debug output, stop that debug and start the next debug, attempt ping, and cycle through the list:
- debug dialer (this will show whether the router believes that it should bring up the ISDN. I would expect it to show attempts at dial activity - if it does not show dial attempts then do not run the other debugs).
- debug isdn q931 (this should show the ISDN dialing activity and whether there are ISDN issues preventing the call)
- debug ppp negotiation (if ISDN dials the call then this will show the router attempting to make the PPP connection)
- debug ppp authentication (if PPP is negotiated this will show whether there are problems in authentication).
Post these debugs and we will see what they show us about the ping not working.
