Based on your symptom -- pings work until you remove a dialer string.

and this is a guess -- with no dialer string and no map the "broadcast"
capabilities are not defined on one side. If the ping instigates an ARP it
would be unsuccessful.

Subject: ISDN issue

Is ther a problem with my ISDN switch, or am I just doing something wrong?

This is my basic isdn configuration:

R6
interface BRI1/0
 ip address 133.10.80.1 255.255.255.0
 encapsulation ppp
 dialer string 5555001
 dialer-group 1
 isdn switch-type basic-ni
 isdn spid1 50355560010101 5556001
 isdn spid2 50355560020101 5556002

R5
interface BRI0
 ip address 133.10.80.2 255.255.255.0
 encapsulation ppp
 dialer string 5556001
 dialer-group 1
 isdn switch-type basic-ni
 isdn spid1 50355550010101 5555001
 isdn spid2 50355550020101 5555002

Pretty simple, right? I have ping connectivity from either side to the
other.
If I remove the dialer string from one side or the other, ISDN seems to come
up normally, but I can no longer ping. Is this normal?

Thanks
