Can anyone spot a problem with this configuration as to why it may not be
working - R1 is connected to R2 with an isdn switch.
r1

Do I need authentication on that Bri 0 interfaces for OSPF for area 0?
I might need ip ospf demand circut on both sides or my authentication could
be faulty.
Any suggestions much appreciated
