Yes, repeatly.
Turns out community `none` doesn't work for removing `no-export`;
picking another community (I used a random 242) does remove the sticky
`no-export`
Go figure.

I know this is a stupid question (if there is such a thing) but did you
remember to clear your BGP sessions on both routers?

Subject: Stripping off the no-export community?
I just did something I thought should have worked, but didn't.
I was tagging five bgp routes with `no-export` leaving router R2 with an
outgoing route-map.
On it's direct neighbor I stripped off the `no-export` on one of the
routes with an incoming route-map.
Using the show ip bgp comm. command, the route-maps worked; but the
route still isn't being passed to the next AS.
Does this sound like normal behavior?
