Sounds like you've got it. AS 100 sends a route to AS 200 with the
"no-export" tag set. AS 200 takes the route, and uses it, but doesn't send
it out to AS 300. AS 300 is either kept in the dark, or learns about the
route via a different path.

Subject: No-Export [7:9565]
Can someone explain what exactly the no-export command is used for in BGP.
I am having problems getting this comand to work the way I think it is
supposed to work. Maybe I am off base in my definition of it, but I am
using Halabi's book as reference.
Basically I have a peering session with a bgp peer and I am advertising a
single route to them. This route is then taken by my peer and being
readvertised to the world and back into my network at another location
(asymetrical routing). I have a hard time getting my bgp neighbor
administrator to make changes for me, so I want to stop the advertisement of
the bgp route outside my neighbor's network (as number) using the no export
command. Is this the correct application for no export or are there better
ways of skinning this cat? Where is my logic being lead astray? Thanks in
advance for any help.
Thanks
