Thank you for your reply.
The problem as you said was with the redistribute connected and not allowing
the serial link through.
I had really been struggling with this.
I am still trying to figure out rules on how to redistribute connected and
whether to lump it in the routing protocol or not. I take it redistributing
connected with one of the interfaces in another routing protocol can cause
loops (?).
