Hi
I've got OpenBGPD running on 3.7, currently whenever I bring up a
session with another peer the session drops to Idle as soon as a set of
routes are learnt.

#macros
BD01="217.112.a.b"

AS 64513

router-id 85.234.132.65
neighbor $BD01 {
  remote-as 29550
  descr BD01
  multihop 3
  local-address 85.234.132.65
  announce none
}

deny from any prefix 10.0.0.0/8 prefixlen >= 8
deny from any prefix 172.16.0.0/12 prefixlen >= 12
deny from any prefix 192.168.0.0/16 prefixlen >= 16

deny from any prefix 224.0.0.0/4 prefixlen >= 4
deny from any prefix 240.0.0.0/4 prefixlen >= 4

The routes in particular are

This behaviour has been observed when bringing sessions up against other
routers too. Is there a way of getting bgpd to log more information as
to why the session was torn down, rather than just logging state
changes. I would speak to AS6871 about the problem but as yet I havn't
worked out what's going wrong.

I tried logging everything with
log updates
dump all in "/var/log/bgp.log"

However when I look at the log with route_btoa it reveals nothing of
what brought down the session.

If I have left out anything pertinent beat me with a clue stick.

Thanks for any help you guys can give me.

Pete
