ISDN Dial Backup can't ping other side

I've set up 2 3640's for dial backup.

When R1 Serial Int goes down, Dialer comes up, Dials via BRI to R2. Connection establishes, Authenticates (CHAP) normally, but I can't ping R2 from R1 or Visa Versa.

Anyone have any ideas?

Can you post your configs?

Re: ISDN Dial Backup can't ping other side

make sure to use the exact names (case sensitive) in dialer-map statements if you are using it. Anyway, we need to see the configs from both with following debug

debug isdn q931

debug dialer

debug ppp nego

term mon

Here is the link for config and troubleshooting etc
