Kuldip,
Does your tunnel come up and stay up. I am thinking if you are running
into a recursive routing lookup situation because the routing protocol
outside the tunnel you are using is RIP which has less attractive
admin distance than OSPF.
My impression was you don't need to make 'area0' contiguous unless the
lab asks you to do so i.e it is ok to have a partioned 'area0'. Though
it's not a recommended design practice but it should work ok. Shall
like to hear opinions from other members regarding this.
