I have two routers linked via a 56k circuit. I have installed ISDN as a backup line and can successfully make manual calls to the remote end. However I can't seem to route traffic over the ISDN line. The serial (56k) is not running unnumbered and is network 192.168.121.0 255.255.255.0 The near end has a static route for this 192.168.121.0 network pointing to the remote ends serial ports IP address (192.168.121.2). On the remote end, no ethernet ports are enabled as I connect to an x25 network via a serial port. So TCP to X25 translation is taking place on this remote router.
I have tried using a floating static route with no success. Would the remote end having no active ethernet port be a issue? If so I was thinking about creating a loopback interface on that end and using the command "ip unnumbered loopback1" for the BRI0/0 port.

interface we use the VLAN tag to demultiplex the VLANs. The switch needs
to determine which MAC Address table to look in for a forwarding
decision. To do this we require the switch to do...
