Hello Again list, problem solved, it wanted to completely refresh the session
to the IXP, issuing "bgpctl neighbor IXP_PRIMARY clear" and "bgpctl neighbor
IXP_SECONDARY clear" openbgpd started to announce peer ASes.
So now a
question to OpenBGPD team: this is a bug? or an undocumented procedure?
Thanks again for your great work on Routing Daemons

Subject: OpenBGPD help on announce needed :)
Hello list,
I am
experiencing a very strange behavior of an newly installed
OpenBGPD router
running on OpenBSD 5.3 with all patches as of two days ago
from errata page.
This Router connects to internal Route Servers and it Peers
with an IXP, i
have tried many parameters but i am failing to announce other
ASes that are
behind me to the IXP it only announces my AS not others. Can
someone shed some
light on this?
Thanks in advance :D
My AS65500, my peer
AS65501 and IXP
AS65000
prefix information:
* i am learning the route from
another Router
through Route Servers these are all connected to
192.168.128/25):
