If you leaked once and they have a teardown setup on the Juniper end
w/o a timeout, it won't let the neighbor reconnect until the session
is cleared. I've seen in IOS 15.x just a few days ago where it had
stuck advertising routes that it shouldn't be, though that was between
two Sup720 based pieces of gear, so probably unrelated (just a data
point that it can/does happen in IOS in general where it's advertising
routes that it insists it isn't)
