Hi Carl,


You need to filter out the default route from the updates of Router B that are sent to router C.


For this you can use a prefix-list or a route-map in the approriate "neighbor x.x.x.x prefix-list yyyy out" or "neighbor x.x.x.x route-map yyyy out" command.


Don't forget to use the "clear ip bgp x.x.x.x soft out" command to refresh the bgp table of the neighbor.


Do you need a more detailed description of the config?


Cheers:

Istvan
