If you want to allow only BGP A default notice to its neighbors EBGP routing, but not any other routing information, I allocation 1.1.1.1 defualt-information route-map at neighbor
Route-map permit at 10
Match 0.0.0.0
Work?
Nobody back? ? ? I top
Why use BGP neighbor to neighbor sent default route? not directly allocated default route? I think that the publication of default : BGP routing, it would have been a lot of flow DOWN off. Nor do routing control.
