DECNET over ISDN

Hey everybody,

I am working on DECNET over ISDN. I have a serial connection between two
routers and I want the ISDN to be used if the serial fails. My interesting
traffic for the BRI is DECNET only, not DECNET routing. The problem is when
the serial goes down. If IP activates the ISDN, the DECNET routes enter the
routing table. However, when the BRI closes the routes age out of the
routing table.

R1---------Serial-------------R2
 \ /
   \ /
     \ /
       \------ISDN-------/

My solution was a DECNET default route. However, if I use the distant
DECNET address as the destination, the routing fails because the recursive
lookup for the distance route has aged out. If I use the interface as the
destination, the encapsulation fails because the dialer map uses the distant
address.

Anyone have a solution?

Thanks,
