Someone ask me about proxy AS. Haven't heard it before and didn't see any doc about it.
But I have a theory that it's like this:
Router1 is running BGP AS1
Router1 has route-map configuration for AS2 to make it look that AS1 is peering downstream with AS2
Router1 is now proxying for AS2.
Router1 is advertising both AS1 and AS2 to its upstream and make it look that AS1 is a transit for AS2.
Has anyone heard it before? Any idea what it is?
