Maureen,
Thanks, I am trying to acheive the second senario, however I have just
matched on the IGP prefix and I get a default generated without the IGP
prefix in the BGP table.
I believe the requirement was that "if" the IGP route was in the BGP table
the default is generated.
The nei XXXX default-originate route-map seems like the right solution
though.
Thanks for your help
