I have set branch offices connected to central office using leased lines and ISDN lines as backup.The dialer interfaces configured in braches to dial to central office are dialing to central office when leased line goes down but not able to exchange the routing table and not even able to ping to central office.can you through some light why ? From branch office when I try to ping to central office dailer interface IP address, ISDN line is getting connected( show isdn active is showing the connection) but not pinging.
I have verified the configuration and the problem is Central Office router not able to map the dialer interfaces to Physical BRI interfaces.It is found out when I see " Show interface DialerX ". But when I see "SHOW ISDN ACTIVE" router showing the active connections.
If you are finding the mapping between dialer interface to BRI is not happening, then chk whether the dialer pool is configured in the dialer interface and whether that particular BRi interface is configured as a memeber of that dialer pool.
Just try debug dialer command and see whether it will indicate the following for an outbound call:
*Mar 1 07:20:45.676: Di15: Cannot place call, no dialer pool set
if this is case, Configure the dialer pool command on the dialer interface.
Or If the physical interface is not associated with any pool, the debug message on the calling router will be the same as in the case where no more physical interfaces are available, causing the fast idle timer to trigger
*Mar 1 11:54:14.937: Di15: No free dialer - starting fast idle timer
Configure the dialer pool-member command on the physical interface to associate it to a dialer pool
If still it not solves ur problem, could u post ur config. so that we can also deal better.
