Hi David,
sorry, I forgot to mention that you need this the " soft-reconf in" (in my configs it is the default)
Also remember the "no rib-out disable" in the router bgp config (this is also default in my configs) to get an output when you use the "advertised-routes" keyword.
what's magic?
received Display information received from this neighbor
received-routes Display routes received from this neighbor (before inbound policy)
So with "received-routes" you will see all routes which the bgp peer is sending to you.
So "received-routes" - "received" = "dropped"
Gruß
Bernd.
