Hmm. That's strange. Does it work after waiting a longer time? bgpctl show can block for some extended time (if the RDE is busy) but you should get a result back. > Also regardless of a reload, attempting to show rib nei a.b.c.d out > also just seems to hang > > bgpctl show rib nei 80.252.124.1 out > flags: * = Valid, > = Selected, I = via IBGP, A = Announced > origin: i = IGP, e = EGP, ? = Incomplete > > flags destination gateway lpref med aspath origin > > and no more output > You're right we have a polling issue here. I'm looking into it. In short, the RDE blocks and does not continue to process the show command until an update or some other message was received because the current batch of work did not queue any outgoing imsgs. The poll(2) timeout needs to be changed to 0 in this case. -- :wq Claudio
